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, more a demonstration to help understand access modifiers for classes, methods, and variables alongside the different types of a variable like a reference or primitive and local or instance, along with the new concepts of static and final variables and the this keyword. The completed code is in the chapter 8 folder of the download bundle. It is called Access Scope This And Static.
Create a new Empty Activity project and call it Access Scope This And Static. Leave the Activity name at the default, MainActivity.
Note
Creating a new project will hopefully be straightforward by now. Refer back to Chapter 1 if you would like a refresher.
Create a new class by right-clicking on the existing MainActivity class in the project...
