class Swap{
 public static void main(String args[]){
  int num1 = Integer.parseInt(args[0]);
  int num2 = Integer.parseInt(args[1]);
  System.out.println("\n***Before Swapping***");
  System.out.println("Number 1 : "+num1);
  System.out.println("Number 2 : "+num2);
  //Swap logic
  num1 = num1 + num2;
  num2 = num1 - num2;
  num1 = num1 - num2;
  System.out.println("\n***After Swapping***");
  System.out.println("Number 1 : "+num1);
  System.out.println("Number 2 : "+num2);
