/*
  Author  : Michael Robinson
  Program : overloading.java  
  Purpose : Using the same method name for multiple methods.

            By having different amount of variables being 
            accepted, and/or different data types, we can
            use methods with the same name.

            This will allows us to use the same method name
            passing multiple variables of different data types, 
            like when we using the print commands.
