ABSTRACT
It is now time to put to work your knowledge of object-orientation and your skills in Java programming. So far we have been dealing with small programs that contain a single class. Our programs have used static variables andmethods. In fact, we have turned off object orientation and used Java as a semi-procedural language. But the advantages of Java are related to its object-oriented features. At this point you are ready to start developing true object-oriented programs and learning to use the OO features of Java.
