bubble sort in java example ascending order

Example 1: bubble sort java

public class BubbleSortExample {  
    static void bubbleSort(int[] arr) {  
        int n = arr.length;  
        int temp = 0;  
         for(int i=0; i < n; i++){  
                 for(int j=1; j < (n-i); j++){  
                          if(arr[j-1] > arr[j]){  
                                 //swap elements  
                                 temp = arr[j-1];  
                                 arr[j-1] = arr[j];  
                                 arr[j] = temp;  
                         }  
                          
                 }  
         }  
  
}

Example 2: Java program bubble sort in ascending and descending order

// Bubble sort descending order
import java.util.Scanner;
public class BubbleSortDescending 
{
   public static void main(String[] args) 
   {
      int number, a, b, temp;
      Scanner sc = new Scanner(System.in);
      System.out.println("Please enter number of integers: ");
      number = sc.nextInt();
      int[] arrInput = new int[number];
      System.out.println("Enter " + number + " integers: ");
      for(a = 0; a < number; a++) 
         arrInput[a] = sc.nextInt();
      for(a = 0; a < (number - 1); a++) 
      {
         for(b = 0; b < number - a - 1; b++) 
         {
            // logic to sort in descending order
            if(arrInput[b] < arrInput[b + 1]) 
            {
               temp = arrInput[b];
               arrInput[b] = arrInput[b + 1];
               arrInput[b + 1] = temp;
            }
         }
      }
      sc.close();
      System.out.println("Sorted integers: ");
      for(a = 0; a < number; a++) 
         System.out.println(arrInput[a]);
   }
}
