This page documents what we do in class. It contains Java programs that we will discuss in class, simple homework exercises that you can work on for practice and exam preparation (not for credit), and reading assignments from our textbook.
The reading assignments and practice problems are listed by the date on which they were assigned. The sample program files are listed by the date on which they were used. You can click on either a .java link and see the source code, or click on a .html link (when available) and see an applet running. When you are viewing the source code, you can use your browser's "File -> Save As..." menu item to save a copy of the file on your computer. It is a good idea for you to "play" with these example programs; compile them, run them, make simple changes to them and compile and run them again.
