In my next column, I'll look at more OOP concepts, such as encapsulation and abstraction, and expand on how you can use data/variables in Java. We'll add more functionality to our AlarmClock class, and we'll begin to look at how to build classes.

For homework, you can take a look at the documentation that comes with Java. You did install that on your system, right? If you installed Java in C:\jdk1.2.2, then the API docs are in file:///C:/Apps/java/docs/api/index.html. Go there and look for the String and Calendar classes in the frame titled "All Classes." We'll be using both of these classes soon, and it's a good idea to start getting used to this documentation. It will be your friend. Enjoy!
