8. Using and defining objects

This section deals with calling object methods, and with the defining, compiling and use of object classes. In addition, the use of the main() method to control the calling of object methods is discussed. This will instruct us as to the way in which an application is built in Java, and the way in which the main() method is used to direct application code execution. Object method calls (messages) to other object's methods outside of the main() method, will also be examined.

Finally in this section, we examine the javadoc executable, which allows us to build special documentation files for our Java classes. This will include an explanation of the special comment types used in Java and what they lead to.
