Memento Design Pattern

From the creator

Get the Copy and Paste Code: http://goo.gl/rzW5i 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.
