        //create Scanner instance to get input from User
        Scanner scanner = new Scanner(System.in);

        int number = scanner.nextInt();

        System.out.println("Enter second number to add :");
        int num = scanner.nextInt();

        //adding two numbers in Java by calling method
       int result = add(number, num);

       System.out.printf(" Addition of numbers %d and %d is %d %n", number, num, result);
    }
