How to find maximum and minimum value in java using for loop. Commented Oct 9, 2015 at 17:12.

How to find maximum and minimum value in java using for loop maxValue = inputArray[i]; } } return maxValue; } // Method for getting the minimum value And use that value as your maximum and also minimum. Min will hold minimum value node, and max will hold maximum value node. To do it you can use following idea: min(a, b) = (a+b)/2 - |a-b|/2 and max(a, b) = (a+b)/2 + |a-b|/2. in); int maximum = Integer. Anyway, I will tell you how you can find some elements without a loop: To get the max value of an ArrayList you don't need a for. At the end of the loops just print the last highest palindrom and its i and j values. (The only default values that wouldn't cause problems are smallest = Integer. collect(Stats. but instead of doing so directly it's cleaner in my opinion to track the indices of the min and max elements. MAX_VALUE; min = Math. MAX_VALUE and Double. naturalOrder() instead of Comparator. In Java 8, Collections have been enhanced by using lambda. Java Program to find largest and smallest of N numbers without arrays Here is our sample program to find the smallest and largest of N integers without using an array. Changing "16. If you do that, you should also change the for loop to only iterate over the elements you assigned to the array (indices 0 to count-1), and not the entire array. It is highly recommendable to split the computational part from the input/output. In this rental program I need to display the user with maximum and minimum rents. No, you wouldn't. The simplest method to find the maximum and minimum element of the array is iterates through the array and compare each element with the assumed minimum and maximum and update them if the current element is smaller or larger respectively. You don't want to compare using strings but by the natural order of your double elements, i. It's an initialization trick, in case the list is empty, it will return infinite, meaning with that that the Explanation on Integer. 258k Integer. def max_min(iterable, key=None): ''' returns a tuple of the A user should input a number "x", and then the count of "x" numbers, e. The algorithm to find the maximum and minimum node is given below. ; If the size There is a O(n) solution if you find the 3 maximum and 2 minimum values in linear times. max(max, element); min = Math. I'm trying to find minimum maximum element in array and then delete the minimum and maximum. Java cannot easily return two values from a method. println("Maximum number "+max); use a for loop instead of a while loop (you need intialization, condition and iteration) use the JDK's API more - Math. MIN_VALUE returns the largest and smallest number that is representable by an Integer value. // Now check if the guess is correct and update if you are wrong. Lets say that you want to add the names of some student and you also want to save the corresponding marks obtained by each student. Make a separate assignment to smallest altogether before the loop begins. However, a recursive solution will require less comparisons than naive algorithm, if you want to get min, max simultaneously (it isn't necessarily faster due to function call overhead). // when you have checked all the values exit the loop. let us calculate those values we're after: Calculating the sum is easy: min and max in java. MIN_VALUE and smallest number are initialized with Integer. How to find the min / max value using for-loop. I have implemented a for-loop to find the max value just not sure how to isolate to each column. MIN_VALUE. Then it returns the number of values, the min/max, and average value. 4,NA,NA,NA} so Ignore a By initializing the min/max values to their extreme opposite, you avoid any edge cases of values in the input: Either one of min/max is in fact one of those values (in the case where the input consists of only one of those values), or the correct min/max will be found. I searched this but did not find it. The original few lines does not make much sense, because minDistance < distance would never evaluates to true since you just set minDistance = distance; distance = calculateHotSpot(point1, point2); . Output : max = 20, min = 1. // if it is smaller than update your guess. But you can also use nlog(n) sorting (i. How to find "max" 0. For one of the questions i was asked to solve, I found the max value of an array using a for loop, so i tried to find it using recursion and this is what I came up with: Firstly you need to understand a lot of thing with you code is wrong. What is an Array? In JavaScript, an array is an ordered list of values. min( next, minimum); Given an unsorted list of integers, find maximum and minimum values in it. Example 4: Using a For Loop with ifelse Function Here is naive way of finding find minimum and maximum value in an unsorted list where we check against all values present in the list and maintain minimum & maximum value found so far. thanks. Instead, in you add method, you need to be comparing the values as they are added, you can use Math. It's trivial to write a function to determine the min/max value in an array, such as: /** * * @param chars * @return the max value in the array of chars */ private static int maxValue(char[] A straightforward solution: def minimum(lst): n = float('+inf') for num in lst: if num < n: n = num return n Explanation: first, you initialize n (the minimum number) to a very large value, in such a way that any other number will be smaller than it - for example, the infinite value. Hot I had the same problem, I needed to obtain the minimum and maximum values of an array and, to my surprise, there were no built-in functions for arrays. Here, we have given a list of numbers and we have to find the smallest number in given list by using different methods, such as min(), for loop(), and sort(). Follow answered Feb 8, 2022 at 15:21 . No loop required, use max method from java. Then you should fix the classic mistake in implementing the min / max: you should either. Your for loop that finds the minimum should be after the while loop that reads the input, not inside it (since currently it goes over un-initialized elements of the array, so it always finds a 0 as the minimum). Loop through data from 0 to data. 1 Enter an input value: 8 Enter an input value: 3 The maximum is: 23 The minimum is: 1 Share. doubl I've got a homework assignment where I need to write a program using a loop that takes 10 integer values from a user and outputs the minimum of all values entered. MAX_VALUE and Integer. length; i++) { System. But i have a hard to find out the solution. @AndySenn using Java is one such piece of overhead. I have literately tried everything from writing separate methods and so on and still the output in 0. Commented Jan 14, 2014 at 16:30. MIN_VALUE OK, I have been at it for a long time now. Sorting. max(double a, double b) and Math. Scanner infile = new Scanner ( new FileReader(args[0]) ); int count=0,sum=0, largest=Integer. for(int ii = 1, j = 0; j <= copySel ; ii++, j++) { //btw, what is 'j' for? attempt I am trying to resolve an excercise about finding out the lowest value in array using loop. MIN_VALUE and lowest = Integer. Keep in mind I'm at a very rudimentary level, and I have not reached arrays In the case that you only want to go through your iterable once, (say it's an expensive operation to do, and really that's the only reason you should do this, instead of doing max or min separately, but that said, the below is a performance improvement on calling both separately, see numbers below):. mapToInt(Integer::intValue Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Then just iterate through the list, comparing each element to the current minimum and maximum elements: Comparator<Entry> comparator = new EntryComparator(); Iterator<Entry> it = list. collector()) fooStream. Use a loop to iterate over the array, starting from In this approach, a loop is used in combination with Math. Finding largest number in Java. min method. Otherwise output first minimum value, then maximum value. getting stuck on For a start you can use Math. out. MAX_VALUE and then the first iteration will end up with the correct highest and lowest value. This It initializes max and min variables to the first element of the array. (Though the bands might be in a different order depending on the library you're using In python there are many ways to get minimum and maximum from a list by using different method such as using min() and max() function, by using “for” loop, and by using sort()function. Using java write two methods min and max to find maximum value and minimum value in linked list but the input list is array of integers Hot Network Questions Sous vide pouches puffed up - Is this product contaminated? See the below modification. stream(). length ; i++) // Need to In this video I will show you how to find the highest and lowest number among all the inputs using Java Netbeans. This is obviously a "Learn Java" class, not an algorithms class. Getting min and max values from an array - Java. The average is sum / count. First of all, you can implement function sort(a, b), which returns pair of sorted values. But here you have function |x|=abs(x), which uses 'if' inside. I need to find the maximum values within an array and minimum values. The conversion of the array to a list has a constant time complexity of O(1), and finding the minimum and maximum values involves iterating Because of the way you choose the random values in a, there will be no value less than zero - but there is also no guarantee that any of the values will be exactly zero. Algorithm. 5,4. Maximum and Minimum using loops. Code: Given an array, write functions to find the minimum and maximum elements in it. and want print total max min average I found total,max &amp; average using this code import java. You never calculate the max and the min value in your loop. Java 8 Stream min and max method example : Introduction : In this tutorial, we will learn how to use min and max methods of Java 8 Stream to find the minimum and maximum element in a list. So I worked on this for a bit and I think I have something close to what you're looking for using a do while loop. MAX_VALUE (yes, MAX value) and max to `Integer. 0" to "92. *; class Using Java 8 you can do this very easily traversing the list only once: IntSummaryStatistics stats = al. This I want to find the maximum and minimum value by the for loop, but problem is that when array value is start from a maximum number like (100,30,50,60) then output is the correct first maximum value then, minimum value. Hi I'm having a problem to write a loop which finds the largest value. Hint : In this loop, find the max and the min value. split in order to find entries for a particular k value. So, you only see the code enter the if block once and print only once. hasNext()) I've written the code for the listed variables within the while loop but I can't figure out what to do about the largest and smallest value. MIN_VALUE; int min = Integer. Commented Oct 8, 2022 at 8:37. MAX_VALUE to make sure that negative values are handled. Input : list = [10, 400, 3, 2, 1, -1] Output : max = 400, min = -1. An example: a = [1, 3, 7, 2] You initialize largest = 0. If you are I was wondering while using java. 0") is greater than 1 (of "16. Java Program to find the maximum element of an array. Just set min initially to Integer. It might seem a good idea to use a . MIN_VALUE or Double. Comparing via strings will result in the characters being compared and since the character value of 9 (of "9. And then, what you are doing is to always get the minimum of two values, so this can be simplified by using the Math. You code works for max only by accident :) Try entering only negative values to the input and your max will also give only 0. Obviously, I can loop over the array twice and use ~2n comparisons in the worst case but I Using simple for loop. util. public Finding the maximum and minimum values of a List using the max() and min() methods from the Collections class. . Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company I was asked to write a program to find the minimum, maximum, average and sum of user inputs and I came up with the following program but there seems to be a problem with the loop I'm using because the program just exits when compiled. iterator(); Entry min, max; // Assumes that the list is not empty // (in which case min and max aren't defined anyway). Add a comment | 4 Answers Sorted by: Reset to default 2 . MIN_VALUE; for(int x : values) maximum = (x > maximum) ? x : maximum; return maximum; } Loop to find max value. So the solution is a one-liner, and you can either obtain the entry or the key Your highest and lowest variables both start at 0. The code used to find all occurrences of the minimum value element can be found here. One common task is finding the maximum and minimum values in a list or collection. In particular, the minimum value should be seeded with the maximum possible integer value, and the In this article, we will discuss different ways to find the maximum and minimum elements of the array in C. I think that once you go into the while loop you will never get the new min/max/avg calculated. Hot Network Questions Is there a way to find out the Maximum and minimum of an array consisting of integer, floating point number and string or characters? in java for example: A={1,2,3,4,4. 0" The line largest = array[i]; does NOT mean 0 = array[i] as you believe. int[][] test = {{3, 9, 3, 5}, {4, 19, 4, 9}, {2, 10, 5, 6}}; I want to find the max value in each row in a two- I want to find the max value in each row in a two-dimensional array, and I wonder how to code it. Like, //Find maximum Math. I need to write a program that reads in an arbitrary number of data points from standard input. – Kevin Anderson. Initialize your smallest value to Integer. //Find maximum (largest) value in array using loop System. java- find minimum/maximum in an entered set of numbers. MIN_VALUE' and loop alone will take care of everything. So if your numbers are all negative, you'll get a highest of 0, incorrectly. Scanner scan=new Scanner(System. For both ’max’ and ’min’, we will pass one You can't know what the max or min is until after the loop has completed, so you can't print either before that. You have not read any values at this point, so initialize your min and max values with: int max = Integer. Commented Feb 8, 2022 at 15:20. After reading a lot, I decided to test the "top 3" solutions myself: discrete solution: a FOR loop to check every element of the array against the current max and/or min value; I am working on this program to find minium and maximum values of the variable milesTracker and have been successful for a few tests but it breaks testing it with values {{-5}, {-93}, {-259}}. MIN_VALUE,smallest=Integer. int max = Integer. writing java code to find max&min. If it is higher than the saved value store the new value as last highest palindrom. Also, if you need to use only 4 There was some confusion as to if the findMin method returned the minimum value, or the minimum index. Then the elements are read using the scanner class. g using stream, generate n number between min and max // randomRandom(min, max) example of getting one random number between min and max // randomMath(min, max): other way similar to randomRandom(min, max) // randomThreadLocalRandom(): just for a random number without constrain // It is effective way I guess you are trying to get the minimum value from the current input and last minimum value. Commented Oct 9, 2015 at 17:12. MIN_VALUE is a regular double, I don't see the need for the Double type. MAX_VALUE'. Create two variables ’max’ and ’min’ to hold the maximum and minimum values . In the above example, 1 will be minimum value node and 8 will be maximum value node. Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Your question is not that much explanatory. The keys for a concise, efficient and elegant solution here are the Collections#min method and the Map. It now returns the minimum index. MIN_VALUE to find min and max value in an array below is a code snippet of finding the largest and smallest value from a loop. so my homework question is prompt user a series of integers and find the max and min of those integer. MAX_VALUE and max at Integer. You initialize min to 0, and no number you input is ever going to be less than 0 (assuming you're only entering positive numbers), so min will always be 0. If this is a frequently needed feature, we better make a Collector to do the job. max(Math. In the Comparison in Pairs method, we'll implement the following steps. However, you initialize m to be zero, since that is the default value of the array elements; nothing can be smaller than this, so the answer is always zero. max() spell "accumulator" correctly; remove all variables you are not using (cnt) Try this: No, it's seriously not worth changing. So maximum = 20 and minimum = 20. – Scott Hunter. Stats<String> stats = stringStream. 2. ; I prefer the second approach, because it keeps explicit initialization out of the code: ahhhhh, i understand now, every time 1 loop finishes, max has new value and depending on whether it's bigger/smaller and the arrow direction it will change – Jakub Mazurkiewicz. min() the methods that find only maximum and minimum of 2 numbers. There are two-dimensional arrays as shown below. At the end of your loop you can simply print out maxIndex1, maxIndex2, minIndex1, and minIndex2. To print the minimum and maximum number in an array, user has to create an array with integers. The sort of improvements you're going to get when fiddling with micro-optimisations like this will not be worth it. minimum of list to maximum of value in Javascript. All the elements are further compared through Finding the Maximum and Minimum value in python using loops. How would I determine the I'll simplify this a bit. max() after converting the array to a list is O(n), where n is the number of elements in the array. Typically you'd then start the loop counter from 1, since the 0th value is already dealt with: for(int j=1; j<array[i]. Assuming that what you are trying to do is find the largest and smallest integers are in an array of integers: max value of iterator in for loop in java. These are very I am trying to take 10 integers from the user's input and find the minimum value using a for loop. The minimum loop seems to be correct as you have it IF you initialized the min variable outside the for loop. MAX_VALUE, evens=0, odds=0; double average=0. MIN_VALUE; int minimum = Integer. Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Doing a project for AP Computer science, and I still haven't managed to figure out how to do this part: The program is supposed to ask the user for 5 test score inputs and then the code will "curve" the smallest value entered by taking the square root of the score and adding the integer value of the square root to the original score. length: Sort data[i] Check if the first value of data[i] is less than the minimum and change it if it is. Here is the code to do that. Hot Network Questions Consequences of the false assumption about the existence of a population distribution in the statistical inference, when working with real-world data I am trying to find the max value in each column of a 2d array in Java. Without adding those value into array is there any efficient java code for get the maximum value from that five value set. This appears to be correct. max() In this approach, a loop is used in combination with Math. you set min and max on 0 and then, in for loop, you check if it is less than 0. Share. min(min, 9); min = Math. It is supposed to take the Math. max( next, maximum); minimum = Math. I added variables to track the indices of the min and max. MAX_VALUE; for( int i=0; i<10 && scan. Start min at Integer. max(maximum of a and b,c) gives // the maximum value of a,b,c int max=Math. For example Double. The else block is causing what OP I want to input 10 marks for subjects from user. I am struggling to correctly write the if statement. While summaryStatistics() offers a convenient way to find both the min and max, the Stream API also I would traverse all the rows I have and set the values in these arrays with the maximum and minimum values of each row. min() and Collections. max() functions to determine the minimum and maximum values. You would have to iterate through all values and at each step compare the current element with the smallest one seen so far. MAX_VALUE and I think you'll find it This is a interview question: given an array of integers find the max. 1. The resulting stream then has additional aggregators and collectors specific to integer types, one of the being max(). any idea? //Number serial. Number of Comparisons: The number of comparisons made to find the minimum and maximum elements is equal to the number of comparisons made during the sorting process. I get the five double data type values from five different function. Then in the second for loop we check every value in the array if it is maximal (so checking the first value against a load of zeros) then you exit the nested for loop and print the statement (with the value of a[0], if it was positive). This is my solution using static methods max and min from class Math: Find highest number using if statement in a for loop java. g. So, you see the print statement for as Java Minimum and Maximum values in Array – Karl Knechtel. This can be easily be done using nested loops. Find max values from a array Let's see how to obtain min, max values by using a single funtion. MAX_VALUE; for (int element : a) { max = Math. length; j++){ In a basic java program, I've defined two methods of a class that are supposed to return the maximum and minimum numbers from a set of four doubles. Hot Network Questions How plausible is Comparator. If you have a problem with your algorithm, your best bet is to look into macro-optimisations ("big picture" stuff like algorithm selection or tuning) Since Double. min() and Math. MIN_VALUE and the initial value of the minimum should be Integer. max(arrayList); We will maintain two variables min and max. min(min, 6); // min = 4 Within the loop, update the max_value by comparing the current element value with the existing max_value. Then calculate the range and return it. However, with a simple trick, we can get the maximum of as many numbers as we In this example we are finding out the maximum and minimum values from an int array. Each value is called an element specified by a First, you need to move min and max variables out of the loop. . max to make the comparison easier, for example. In your first loop, when you are computing min/max, you should initialize both min and max to the first value of the array. Whichever value is greater becomes the new max_value. public static int maxValue(int values) { int maximum = Integer. In this tutorial, We traverse an array using for loop to find maximum and minimum value of a How To Find Minimum And Maximum Value In An Array Using JavaScript In this challenge you are going to learn how you can get the maximum and the minimum value of an array using JavaScript. min(a,b),c); // Print them System. comparing. Math. I cannot, however tell you how to calculate average min and max WITH arrays. (average, possible update of the maximum, resetting the variables, etc. for(int loop = 0; loop < 5; ++loop) { // check if data[loop] is smaller than your current guess. util package. Because you're starting at a very high value already, there are several values that are lower than it in the entire array. Using Math. After the loop completes, print the final max_value, which holds the maximum value found in the vector. Set values to both ’max’ and ’min’ as the first number of the list. First of all we need an array. and min. This is a terrible idea because, as you have realised, you have to iterate over the entire map and use String. An example getting a min number without a loop would be: long min = Integer. In Java you can find maximum or minimum value in a numeric array by looping through the array. The Math. Improve this answer (0,len(student_scores)): if student_scores[n]<=min: min=student_scores[n] print(min) # using for loop to go through all items in the list and assign the smallest value to a I need to return the greatest negative value, and if there are no negative values, I need to return zero. Approach 1: Scanner input = new Scanner(System. max(); mapToInt is the key function that describes how to convert the input to an integer type. It then iterates over the elements of the array using a for loop and updates the values of max and min if the current element is greater than max or smaller than min, respectively. I want to some help. You have values larger than that, so largest works. The english version of the question asking to find the max mark for each subject/module. When I test out my code with "5 16" the output is [6, 7]. you may adjust it with your requirement. e. comparing:. None of the values are smaller than 0, so smallest remains 0. Comparator. using minimum comparisons. For an array of string i wil So I'm coding in C, and I need to come up with code that will take n numbers from the user, and find their minimum, maximum, average, and sum of squares for for their values. Scanner; class Example{ public static void You just throw away Min/Max values: // get biggest number getMaxValue(array); // <- getMaxValue returns value, which is ignored // get smallest number getMinValue(array); // <- getMinValue returns value, which is ignored as well Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company @user2994377 In additon to Christian's answer, there is another more subtle bug in your code. Java: find the largest number in a list of I am trying to find the Minimum and Maximum Value in an ArrayList without Sorting: Here is my Current Attempt - However I cannot seem to be getting it to work properly: import java. Introduction Java 8 introduced lambda expressions and the Stream API, enabling developers to perform operations on collections more efficiently and concisely. But as Jeremy said fix your indentation :) – Quantico. largest is a variable, so each time you get to the line largest = array[i]; you are changing the value of largest to be the current array[i]. Even the method call cost will be removed if the min function is called enough. Next step would be to iterate over your set of values and check whether a value is below current minimum, and if so set minimum to that value. max(minimum of and b,c) gives // the minimum value of a,b,c int min=Math. length]; //Array to store the result for(int Not sure where to begin honestly, I was able to find average using the user's input but can't seem to figure out the largest number or the smallest number from the numbers entered. Also, you might use Math. double max = m[0][0]; double min = m[0][0]; //declare variables to track the indices of the min and max int maxIndex1 = -1; int maxIndex2 = -1; int minIndex1 = -1; int minIndex2 = -1; . Then for the other readings, compare the reading to the current maximum and minimum and update the maximum and minimum accordingly. Also, check and see if your value you initialized min to is below any the actual minimum of all of the elements you are checking. For example: // While there is still stuff in the This summary includes the min and max but also provides the average, sum, and count of elements in the Stream. int min = 0; int max = 0; for (int i: list){ //find max and min here } return max - min + 1; I am looking for a way of calculating the minimum and maximum values for a function in Java. 1 @Mumfordwiz - The array that's returned is the maximum red value, the maximum green value, and the maximum blue value. MAX_VALUE. max() and Math. Collections (Documentation) Find a maximum and minimum value using for loop. It is simply a way to find the values more efficiently since they must be one of those values so simply assign the first one. in); int[] numbers = new int[10]; for (int i = 0; i < numbers. Then all you need is to save minimum value from the last turn and compare it with input in the next one. I am struggling with this code. Suppose you have a key that depends on an Integer k and a String s. MIN_VALUE, or; Start both min and max at the first value entered. Create a class Node which has two attributes: data and next. Get Array Elements and Print Cubic Values in Java; Find the Maximum and Minimum Element in an Array in Java; Get Array Elements and Print all Odd Numbers in Java; Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Arrays concepts Java: 1. min(min, 4); min = Math. So, that value at 0th position will min and value at nth position will be max. If you are giving only positive numbers to your program,min value will stay 0 If you want to find min and max value of array you can initialize min and max like this: int min = Integer. Store the according i and j values also. min(a,b) gives minimum of a,b // Then the Math. Definitely it will be the minimum of all the numbers provided. Then you can use a second loop to skip those elements when you copy nums to the new array. If you want to use a loop, then loop with the current max value and check if each element is larger, and if so, assign to the current max. You can use Collections API to find it. The program I am looking to create would see all the local minimums and maximums for a function which oscillates around the x-axis (This is not a school assignment, although I have mentioned cos(x) in the outline below). So far I have the average and sum of squares portion, but the minimum and maximum is biting me. MAX_VALUE int max = Integer. Java Program to find the minimum element of an array 2. In the first for loop we assign the first int to a[0]. Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Why do we initially set min and max to the first value in the array when trying to find the minimum and maximum value? You don't have to set min and max to the first value. finding the second largest value in an array using java. Because this is an int array the values are initialized to 0. int minMax = 0; int smallest = 0; int largest = 0; for(int i = 1; i <= totalNumbers; i++){ System. Please Don't forget to Subscribe(c) Backgrou How do I get the max and min values from a set of numbers entered? 0. min & Math. hasNextInt(); i++ ) { int next = scan. Consider initializing min to some sufficiently large value, like Integer. findMin is also now called only once, not for every iteration in the loop, which is a little cleaner (and slightly faster). Finding the largest Number. How can i get the min value in the simplest possible way // randomStream(n, min, max): e. Improve this answer. MAX_VALUE, so it will be Use the for loop to write a program to prompt the user to enter twelve n amount of numbers and then display the minimum, maximum, sum and the average of these numbers. You should create two double variables called maxVal and minVal. Find highest,lowest and average in a loop. Your max seems to work. min ( min , num ); Three ways to find minimum and maximum values in a Java array of primitive types. I suggest Integer. I'm a newbie in java. utils. The most simplest way to find min and max value of an element is to use inbuilt function sort() in java. Is there a metho The key points to solving this problem are to maintain state for the minimum and maximum values seen which is defined outside the loop. nextInt(); } int min = numbers [0]; // Need to initialize it here outside the loop for (int i = 1 ; i < numbers. So finding max and min can be accomplished as follows, using Comparator. } std::cout << "Smallest: " << min << "\n"; In Java you can find maximum or minimum value in a numeric array by looping through the array. In your loop, as you are getting each double value, use Math. ) You also need the outer loop (in the stated code, these calculations are done for one student only) which you would control in a different manner. MAX_VALUE). This is why you get the max of the array at the end. The excercise is about generics. [GFGTABS] C++ // C++ code for the ap is initializing the maximum value on the ith row to the first value in that row, than scanning the row to find any larger and increase max accordingly. Then in every iteration of the loop you could update your maximum like this: max = Math. Initialize smallest and largest to a valid int from your list of numbers - initializing them to 0 is going to result in smallest equaling 0 when you're finished. 0") you get the result you see. min(double a, double b) should come in handy. MAX_VALUE; private int Collection<Integer> values = new ArrayList<>(); OptionalInt max = values. mozway mozway. The most common method to find and print the largest element of a Java array is to iterate over each element of the array and compare each element with the Stack Overflow for Teams Where developers & technologists share private knowledge with coworkers; Advertising & Talent Reach devs & technologists worldwide about your product, service or employer brand; OverflowAI GenAI features for Teams; OverflowAPI Train & fine-tune LLMs; Labs The future of collective knowledge sharing; About the company Visit the blog Save your product for a later comparison. MAX_VALUE; In fact, you don't need the array at all, since you don't use it after the loop. max(max, valueYouWantToCompare); Finding the correct Java syntax is your task now :-) Good luck! This uses list comprehension to create a new array of all the indices at which the minimum number occurs. min(min, element); } Share. max(a,b),c); // Math. Java Minimum and Maximum values in Array. You should initialize your m = a[0][0] immediately Basic syntax: Some may find it less elegant than newer Java methods. Entry#comparingByValue method. and I can't seem to get how to use this – Mumfordwiz. We'll need a Stats class to hold count, min, max, and factory methods to creat stats collector. This program handles both positive and negative numbers, hence the largest value is initialized with Integer. In java there is no any built-in functions for finding minimum and maximum values of an array, You're initializing the values for smallest and largest to the first element in your array before you've added the values to it, so they're both set to the array's initial values of 0. C I'm trying to get each color's max and min value. in temperatures total = total + value if value > max max = value else if value < min min = value print "Minimum: " min In traditional way, I would have to sort the map according to the values, and take the first/last one. The first method can be applied to the entrySet of the map, and the second one provides a Comparator that compares map Entry objects by their value. min(Math. max() to compare the current double value to maxVal and minVal. Here is what I have: public int greatestNegative(int[] list) { for (int i = 0; i &lt; and initialize minDistance to Double. I want to calculate max and min of five inputs from the user, i managed to get max value but failed to get the min value instead i am getting 0 as my min value which was initialized from before in class Compare. quick sort) to do that job easily. Find min and max value of array. The, for each element of the array you do the following: Single Loop Trick/Comparison in Pairs. Finding Max value in This would be my preference for making the first assignment to smallest variable. It can all be in the loop. Afterwards the program should give an output of the average, min and max value of this "x" numbers. This way we know exactly which is the first statement to assign to smallest, and as others have stated previously get rid of the else block for if statement within the for loop. Just assign the scanner result to an int variable, declared inside the loop. // Then the Math. min The time complexity of finding the minimum and maximum values using Collections. If the size of the array is odd, then we'll initialize the minimum and maximum values to the first element of the array. Traditionally, this required iterating over the collection manually, but with the Stream API, you can achieve this in a Let's go through the process. max. 4. println("Please enter number"); numbers[i] = input. To return the maximum element of the given collection, we can use the max() method, and to return the minimum value, we can use the min() method of the Collections class from the java. How to fix it. nextInt(); maximum = Math. private int smallest = Integer. It should be noted that primitive types must have a value. Map<String, Object> where the keys are k + " " + s (or something similar). input = 3, then 3 random numbers like 3, 5, 7. getting stuck on if there's only one input. Iterate through If you have an array, minimum is often calculated by first setting the initial minimum value to a known maximum value "infinity" or in this case 100. The value parameter is taken in from a for loop, We need to find the maximum and minimum of all numbers within this range. Time complexity: O(n log n), where n is the number of elements in the array, as we are using a sorting algorithm. I have looked after similar problems here in stack-overflow and I still can't make it work. Collections. Initialize max to be the smallest Integer possible; Using the for-each loop check if the current element is larger than max and if so make that the new value of max; Return max after the for-each loop is finished ; Personally I would create a separate method for this: max = 0 min = 0 set up array of a[24] loop start if a[x] > max max = a[x] else if a[x] < min min = a[x] print Max temp: print Min temp: I would like to see how you guys would construct a clear pseudocode of this program. 0; while (infile. min and Math. If you found a palindrom compare it to the last highest palindrom. mapToInt((x) -> x). Because you're starting at a very high value already, there's only one value that's higher than it in the entire array. print out max and min numbers of the input. comparing(String::valueOf). MAX_VALUE: double minDistance = Double. Then here the solution to find the maximum product triplet in C with explanations in comments - The naive algorithm is too loop and update min, max. Auxilary Space: is O(1), as we are not using any extra space. Initialize min_element and max_element with the first element of the array. 0. Use Case: Perfect for those who need a straightforward solution with no additional memory overhead. collector(fooComparator)) Write a java program to find maximum and minimum value in array. println("Maximum Value = " + You have to initialize 'min' value outside the loop, and you must initialize 'min' to large value, something like 'Integer. Min & Max results of a for loop in java. The program works fine for other methods, but it displays maximum value for both max and min. This code accepts user input first, then checks it's value in comparison to the last input and return either "Input a higher value", "Duplicate number found", or it sets the last number entered to the current number. max(x,y) returns the maximum of x and y. MIN_VALUE;) I can tell you how to calculate average min and max without arrays. As it stands, if the first value you enter is also the maximum, the results will be incorrect: It will be less than Integer. Just be sure to initialize your min/max variables properly (Double. print("Number " + i The initial value of the maximum should be Integer. Just start off with highest = Integer. You should declare a max variable and initialize it with some very low value. It then iterates over the elements of the array using a for loop and updates the values of max and min if the current Declare 2 variables, min_element and max_element, to store the minimum and maximum elements, respectively. min(x,y) returns the minimum of x and y. MAX_VALUE; largest = Integer. If your numbers are all positive, you'll get a lowest of 0, incorrectly. int min = arr [ 0 ]; int max = arr [ 0 ]; for ( int num : arr ) { min = Math . Trying to find the minimum is the problem. xtq jjqd byh toxedud itl liq aksivok gfmphq utspf fdyc
