  • To convert GUI applications to applets (§18.2).
  • To embed applets in Web pages (§18.3).
  • To run applets from Web browsers and from the appletviewer (§§18.3.1-18.3.2).
  • To write a Java program that can run as both an application and an applet (§18.4).
  • To override the init, start, stop, and destroy methods in the Applet class (§18.5).
  • To pass string values to applets from HTML (§18.6).
