Day 7: Writing Java Applets

Notes and Corrections

• Several readers have asked why the Watch applet from this chapter does not work in Internet Explorer, Netscape Navigator, or another browser. This is explained in the "Choosing a Java Version" section on pages 165-167 -- the Watch applet uses Java 2 techniques, so it cannot be run by the built-in Java interpreter included with popular browsers. To find out how to make the applet work in those browsers, read the "Developing Java 2 Applets" section on pages 185-189.
