Activity 2 – Factorial class

In an earlier unit you will have written a program to calculate the factorial of a number — a model answer is Factorial1.java.

Modify this program so that it uses a class called Factorial to do the calculation. This class should have a method called calculateFactorial() which contains the code to do the calculation itself. In the program's main class, you should get the answer by executing:

Factorial.calculateFactorial(50);
