        int num2 = 2;
        System.out.println("Before swap method, num1 is " + num1 + " and num2 is " + num2);
        swap(num1, num2);
        System.out.println("After swap method, num1 is " + num1 + " and num2 is " + num2);
    }
    public static void swap(int n1, int n2) {
        int temp = n1;
        n1 = n2;
        n2 = temp;
    }
}

	Before swap method, num1 is 1 and num2 is 2 After swap method, num1 is 2 and num2 is 1
