Java Program to sort the elements of an array in descending order17 Mar 2025 | 2 min read In this program, we need to sort the given array in descending order such that elements will be arranged from largest to smallest. This can be achieved through two loops. The outer loop will select an element, and inner loop allows us to compare selected element with rest of the elements.  Elements will be sorted in such a way that largest element will appear on extreme left which in this case is 8. The smallest element will appear on extreme right which in this case is 1. Algorithm
Program:Output: Elements of original array: 5 2 8 7 1 Elements of array sorted in descending order: 8 7 5 2 1 Next TopicJava Programs |
An array of unsorted integers is given. Our task is to move all the zero elements to the end and non-zero elements to the front. Note the relative arrangement of the non-zero elements should never get disturbed. The following examples make things clearer. Example 1: Input: int arr[]...
