Encapsulation and static methods mini app

We have looked at the intricate way that access to variables and their scope is controlled, and it would probably serve us well to look at an example of them in action. These will not so much be practical real-world examples of variable use, but more a demonstration to help understand access modifiers for classes, methods, and variables. This is alongside the different types of variable-like references or primitive and local instances, along with the new concepts of static and final variables and the this keyword. The completed code is in the chapter 9 folder of the download bundle. It is called Access Scope This And Static.

Create a new blank activity project and call it Access Scope This And Static.
