Write a program to Swap the values

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);
    }
}
