Program

import java.util.Scanner;

public class ExSortInDescending {
  public static void main(String[] args) {
    int n, temp;
    //scanner class object creation
    Scanner s = new Scanner(System.in);

    //input total number of elements
    System.out.print("Enter number of elements you want : ");
    n = s.nextInt();

    //integer arrar declarations
    int a[] = new int[n];

    //input array elements 
    System.out.println("Enter all the elements:");
    for (int i = 0; i < n; i++) {
      a[i] = s.nextInt();
    }

    //sorting elements
    for (int i = 0; i < n; i++) {
      for (int j = i + 1; j < n; j++) {
        if (a[i] < a[j]) {
          temp = a[i];
          a[i] = a[j];
          a[j] = temp;
        }
      }
    }

    //print sorted array
    System.out.println("Descending Order:");
    for (int i = 0; i < n; i++) {
      System.out.println(a[i]);
    }
  }
}
