How to Find the Maximum Element in an Array? Last Updated : 15 Nov, 2024 Comments Improve Suggest changes Like Article Like Report In Java, the array is a data structure that allows the users to store data of the same type in contiguous memory locations. To find the maximum element in an Array in Java, we can sort the array in ascending order using the Arrays.sort() method and then we can access the last element of the array which will be the maximum element of the array.Steps to Find the Maximum Element in an ArrayWe declared a method findMaximum inside the MaxElementFinder class to find the maximum element of the array.Sorted the array in ascending order using the Arrays.sort() method.Returned the last element of the sorted array, which is the maximum element of the array.The following program illustrates how we can find the maximum element in an array in Java: Java // Java program to find the maximum element in an array import java.util.Arrays; public class Main { public static void main(String[] args) { int[] arr = { 20,10,5,40,30}; // Find the maximum element of the array // Sort the Array Arrays.sort(arr); int max = arr[arr.length - 1]; System.out.println("Maximum Element : " + max); } } OutputMaximum Element : 40 Comment More infoAdvertise with us Next Article How to Find the Maximum Element in an Array?

There is an inbuilt function in the ArrayList class to find the maximum element in the ArrayList, i.e. Time Complexity is O(N), where N is the size of ArrayList, Let's discuss both the methods. Example 2 min read Java Program to Find Largest Element in an Array Finding the largest element in an array is a common programming task. There are multiple approaches to solve it. In this article, we will explore four practical approaches one by one to solve this in Java.Example Input/Output:Input: arr = { 1, 2, 3, 4, 5}Output: 5Input: arr = { 10, 3, 5, 7, 2, 12}Ou 4 min read Finding Maximum Element of Java Vector Vector implements a dynamic array that means it can grow or shrink as required. Like an array, it contains components that can be accessed using an integer index. We know two ways for declaring array i.e. either with a fixed size of array or size enter as per the demand of the user according to whic 3 min read Java Program to Find k maximum elements of array in original order Given an array arr[] and an integer k, we need to print k maximum elements of given array. The elements should printed in the order of the input.Note : k is always less than or equal to n. Examples: Input : arr[] = {10 50 30 60 15} k = 2 Output : 50 60 The top 2 elements are printed as per their app 4 min read Java Program to Find maximum element of each row in a matrix Given a matrix, the task is to find the maximum element of each row. Examples: Input : [1, 2, 3] [1, 4, 9] [76, 34, 21] Output : 3 9 76 Input : [1, 2, 3, 21] [12, 1, 65, 9] [1, 56, 34, 2] Output : 21 65 56 Approach : Approach is very simple.
