Session G1: Graphics and Applets

In this laboratory session, you will develop a number of simple Java applets that are displayed in Web pages. The purposes of this lab session are to

• introduce graphics in Java;
• introduce Java's applets, an alternative model of programming; and
• have some fun.

Your instructor will tell you which of the proposed experiments you are to perform.

Note: As the introduction notes, this manual provides two mechanisms for learning about applets. One is this lab. The other is the applet problems that appear at the end of many experiments. If you've been doing the applet problems, you are likely to find this lab repetitious.
