Write a Bubble Sort program in java

import java.util.Scanner;

class BubbleSort
{
  public static void main(String []args)
  {
    int n, c, d, swap;
    Scanner in = new Scanner(System.in); 
    System.out.println("Input number of integers to sort");
    n = in.nextInt(); 
    int array[] = new int[n]; 
    System.out.println("Enter " + n + " integers"); 
    for (c = 0; c < n; c++) 
      array[c] = in.nextInt(); 
    for (c = 0; c < ( n - 1 ); c++) {
      for (d = 0; d < n - c - 1; d++) {
        if (array[d] > array[d+1]) /* For descending order use < */
        {
          swap       = array[d];
          array[d]   = array[d+1];
          array[d+1] = swap;
        }
      }
    } 
    System.out.println("Sorted list of numbers"); 
    for (c = 0; c < n; c++) 
      System.out.println(array[c]);
  }
}

Output

Input number of integers to sort
5

Enter 5 integer
5
4
3
2
1

Sorted list of numbers
1
2
3
4
5
 

Explanation

Complexity of bubble sort is O(n2) which makes it a less frequent option for arranging in sorted order when quantity of numbers is high.
