Swap Two Variables Using XOR Operator Using Java Example

Algorithm for Swap Two Variables Using XOR Operator:

step 1: Read a, b

step 2: a=a^b

step 3: b=b^a

step 4: a=a^b

step 5: Print a,b

step 6: Exit

Here is the Java Example for Swap Two Variables Using XOR Operator:

import java.util.Scanner; 
 public class SwapUsingXOR 
 { 
                  public static void main(String args[]) 
            { 
                   Scanner s=new Scanner(System.in); 
                   int a,b; 
                   System.out.println("Enter Two Numbers"); 
                   a=s.nextInt() ; 
                   b=s.nextInt(); 
                   System.out.println("Before swap"); 
                   System.out.println("value of a is "+a+" value of b is "+b); 
                   a=a^b; 
                   b=b^a; 
                   a=a^b; 
                   System.out.println("After swap") ; 
                   System.out.println("value of a is "+a+" value of b is "+b); 
              } 
 }
