Java Program for Bubble Sort in Descending Order

Write a Java program for bubble sort in descending order. This Java example uses nested for loop to perform bubble sort on the array to sort them in descending order.

package Remaining;

import java.util.Scanner;

public class BubbleSortDesc1 {

	private static Scanner sc;
	
	public static void main(String[] args) {
		int i, j, Size, temp;
		
		sc = new Scanner(System.in);		
		System.out.print("Enter the Bubble Sort Array size = ");
		Size = sc.nextInt();
		
		int[] arr = new int[Size];
		
		System.out.format("Enter Bubble Sort Array %d elements  = ", Size);
		for(i = 0; i < Size; i++) 
		{
			arr[i] = sc.nextInt();
		}
		
		for(i = 0; i < arr.length; i++)
		{
			for(j = 0; j < arr.length - i - 1; j++)
			{
				if(arr[j] < arr[j + 1])
				{
					temp = arr[j];
					arr[j] = arr[j + 1];
					arr[j + 1] = temp;
				}
			}
		}
		System.out.println("Bubble Sort to Sort Integers in Descending Order");
		for(i = 0; i < arr.length; i++)
		{
			System.out.println(arr[i]);
		}
	}
}

Java program to perform bubble sort on arrays in descending order using a while loop. 

package Remaining;

import java.util.Scanner;

public class BubSrtDesc2 {

	private static Scanner sc;
	
	public static void main(String[] args) {
		int i, j, Size, temp;
		
		sc = new Scanner(System.in);		
		System.out.print("Enter the size = ");
		Size = sc.nextInt();
		
		int[] arr = new int[Size];
		
		System.out.format("Enter %d elements  = ", Size);
		i = 0; 
		while(i < Size) 
		{
			arr[i] = sc.nextInt();
			i++;
		}
		
		i = 0; 
		while(i < arr.length)
		{
			j = 0;
			while(j < arr.length - i - 1)
			{
				if(arr[j] < arr[j + 1])
				{
					temp = arr[j];
					arr[j] = arr[j + 1];
					arr[j + 1] = temp;
				}
				j++;
			}
			i++;
		}
		System.out.println("Result");
		i = 0; 
		while(i < arr.length)
		{
			System.out.println(arr[i]);
			i++;
		}
	}
}

Enter the size = 9
Enter 9 elements  = 22 99 55 77 13 88 125 66 30
Result
125
99
88
77
66
55
30
22
