A Good Way to Organize Classes With Java
Package and manage your class libraries to make it more convenient for developers to find and include your libraries. Class libraries are given a name with the main encompassing "com" package, and each sub-class is added with a dot character prefix. This naming scheme organizes your classes and packages for developers to include in projects.

Open your Eclipse Java editor, then open the main class project you want to organize.

Click "File" and select "New Class" to open the new class library wizard. In the "Name" text box for the new class, give a name to the class that follows the hierarchy. For instance, if you make an Android app and the new class is for a website download, name the class "com.android.myapp.web." This organizes the class, so you can find it in a list of libraries.

Add the organized classes to a project. For instance, if you create a new class named "com.android.myapp.web," you must include the hierarchy libraries. Insert the following library to the top of the file:
include com.android.*;
The asterisk character tells the Java compiler to include all files under the Android class hierarchy.
