Abstract

By now you should have had plenty of practice at writing simple Java programs and classes. Some of these programs will have made use of classes developed by other programmers and you should have become accustomed to the way that Java defines and implements a class. The definition describes the public interface to the class and also includes the implementations of the methods themselves. In the last two chapters you got plenty of practice in developing your own classes, and you should now be able to develop your own classes for other programmers to use.
