Description

The Main objective of this lab is to learn how to break down a program into classes, and therefore create a classes with their respective  fields and methods, using method overloading. For instance, in order to do this type of program first you’ll need to create a program called NumberStats to do all the menu for the calculations. Second, you need to create another program called TrainStats this program will have the function of computing all the data from Numberstats using methods and calling each class according to which fields they belong to.
