Trail: Learning the Java Language

Lesson: Classes and Inheritance

This chapter has been updated to reflect features and conventions of the latest release, JDK 5.0, but it is not yet final. We've published this preliminary version so you can get the most current information now, and so you can tell us (please!) about errors, omissions, or improvements we can make to this tutorial.
With the knowledge you now have of the basics of the Java programming language and creating and using objects, you can learn to write your own classes. In this chapter, you will find information about defining your own classes, including declaring member variables, writing methods, inheriting variables and methods from superclasses, nesting classes within other classes, and so on.
