This page documents what we do in class. It contains Java programs that we will discuss in class, reading assignments, simple homework exercises that you can work on for practice and exam preparation (not for credit), and links to other sources of information. It is a good idea for you to "play" with the example Java programs; compile them, run them, make simple changes to them and compile and run them again.
The final exam is Monday, December 11.
