  System.out.println("Before swapping");
  int a = 20;
  int b = 40;
  System.out.println("value of a:" + a);
  System.out.println("value of b:" + b);
  System.out.println("After swapping");
  a = a ^ b;
  b = a ^ b;
  a = a ^ b;
  System.out.println("value of a:" + a);
  System.out.println("value of b:" + b);
 }
}

Step 2: Name it as "sp.java" and save the file in any location. I saved at "C:/kiran/program".
