Reader Questions

• Question: The Watch applet compiles just fine and I can see the working program with appletviewer, but none of my browsers is able to show the applet. Do you have any idea what's wrong? --M.L.
  Answer: The Watch applet is written using Java 2 techniques, so it won't be able to run in a Web browser that doesn't support Java 2. At present, none of the major browser developers offers built-in support for this version of the Java language. The Java Plug-in section of Day 7 describes how support for Java 2 applets can be added to current browsers.

Activities

• Solution #1: WayNewWatch.java and WayNewWatch.class.
• Solution #2: EllsworthApplet.java, EllsworthApplet.class, and EllsworthApplet.html. To see this applet in a Web browser using the Java Plug-in, open EllsworthPlugIn.html.
