How Does an Applet Work

How Does an Applet Work?

• An applet context is needed. This is a program
  such as a browser or appletviewer.
• You tell the applet context to run an Applet,
  which your applet extends, by providing it with
  an HTML file.
• That file identifies the bytecode that defines
  the applet to be instantiated and executed, and
  the height and width of the window in which the
  applet will appear.

What are the methods in Applet?

• init() Initializes the applet and is often
  overriden by the programmer.
• start() Makes the applet active i.e. starts
  the applet running.
• stop() Makes the applet inactive i.e. stops
  the applet from running temporarily.
• Destroy() Is called by the applet context when
  the user exits the applet context and destroys
  the applet.
