Welcome to my Memento Design Pattern Tutorial! The Memento design pattern provides a way to store previous states of an Object easily.

It has 3 main classes:

1. Memento: The basic object that is stored in different states. 

2. Originator: Sets and Gets values from the currently targeted Memento. Creates new Mementos and assigns current values to them. 

3. Caretaker: Holds an ArrayList that contains all previous versions of the Memento. It can store and retrieve stored Mementos.

All of the code is above to help you learn.
