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.
For each chapter of the textbook, it is a good idea for you to also look at the Powerpoint slides that the book's author has prepared. You should download them onto your own computer.

- NOTE:
- The exam, which is Thursday at 6:00 p.m., is supposed to be in G011, the room that we meet in on Tuesdays.
- Thursday, December 7.
- The following programs extend the client/server example from Chapter 16 of the textbook. The program Server3 is a multithreaded version of the server that can handle multiple simultaneous clients.
- Some more example of threads (see the beginning of Chapter 13).
- Here is a better version of a program that we used earlier in the semester to watch how events are generated by different components in a Swing GUI.
- Here is a link to a nice animated movie about how the Internet works (made as a kind of Star Wars parody). Unfortunately, the movie is huge, so don't try to download it at home. You could download it on campus and then move it to a Zip disk.
- Do you really like to program? And do you have a lot of time on your hands? Here is a zip file containing about 40 internet shorcuts to interesting programming web sites that I found over the last semester.
- Tuesday, December 5.
- Here are two references on the Internet for a particular security problem with MS Internet Explorer and Java. The first reference is to where I first read about this security problem and the second reference is to the person who discovered the problem. The third link is to the Java program that exploits the security problem. The Java program is an applet that makes use of streams.

- Read Chapter 9, pages 352-394. (Note: A lot of what is in these pages is reference material about various components. However, what is most important in this chapter are the example programs that use these compoents. These are nice examples of simple programs with GUI's. It is more important to understand these examples then it is to remember all the details about the various components.)

- The next five groups of files give an extended example of how implementation can be separated from the public interface of a class. (There are a lot of files here. If you wish, you can download them all as a zip file).
- The next two files give two different implementations of a Hat class. Both of the implementations provide the exact same public interface. The third file uses the Hat class, and it can use either implementation since the two implementations have the same public interface.
- The next file defines an abstract Hat class and the two files after it give two different implementations of the abstract Hat class. The UseHat program shows how the two implementations of the Hat class can be used at the same time.
- The following six files give an example of using both inheritance for specialization and inheritance for implementation. The AbstractHatItem and AbstractGloveItem classes extend the OrderItem class and they provide two different kinds of items that can be ordered. The HatItemA and HatItemB classes provide two different implementations of the AbstractHatItem class, and the GloveItem class provides an implementation of the AbstractGloveItem class.
- The following example redoes the last example but it uses interfaces to define the public interface of a hat and a glove item (instead of abstract classes). So now the HatItemA and HatItemB classes both extend OrderItem and they both implement the HatInterface. And the GloveItem class extends OrderItem and implements the GloveInterface.
- The following example redoes the last example to show that classes can implement multiple interfaces (but classes can only inherit from one parent class). In this example we add a Returnable interface that an OrderItem can implement and we make the GloveItem class implement this interface. So now the HatItemA and HatItemB classes both extend OrderItem and they both implement the HatInterface. And the GloveItem class extends OrderItem and implements both the Returnable interface and GloveInterface. (Only the files that need to be changed for the last example are given below.)
- Tuesday, October 10.
