Java Program to Swap Two Numbers Using Bitwise Operator

import java.util.Scanner;  
public class SwapTwoNumbersExample1  
{  
public static void main(String args[])  
{  
int a, b;  
Scanner scanner = new Scanner(System.in);  
System.out.print("Enter the first number: ");  
a = scanner.nextInt();  
System.out.print("Enter the second number: ");  
b = scanner.nextInt();  
System.out.println("Before swapping:");  
System.out.println("a = " +a +", b = " +b);  
a = a ^ b;  
b = a ^ b;  
a = a ^ b;  
System.out.println("After swapping:");  
System.out.print("a = " +a +", b = " +b);  
}  
}  

Output:

Enter the first number: 5
Enter the second number: 9
Before swapping:
a = 5, b = 9
After swapping:
a = 9, b = 5
