static method: Calculator Utility

In this problem, you will create a program that reads two integers, computes their sum and product using static methods in a Calculator class, and displays the results to standard output.

Learning Objective: Provide common processing without instantiation using static method

Create a calculator utility class requiring no instantiation. Declare static methods with public static int, and allow direct calls from the class name like Calculator.add(a, b).
