Basic classes app

The generals who will be using our app will need more than one Soldier object. In our app that we are about to build, we will instantiate and use multiple objects. We will also demonstrate using the dot operator on variables and methods to show that different objects have their very own instance variables.

You can get the completed code for this example in the code download. It is in the chapter 10/Basic Classes folder. However, it is most useful to read on to create your own working example.

Create a project with the Empty Activity template. Call the application Basic Classes. Now, we will create a new class called Soldier:

1. Right-click the com.gamecodeschool.basicclasses (or whatever your package name is) folder in the project explorer window.

2. Select New | Java Class in the Name: field.

3. Type Soldier and click OK.
