The Applet's life cycle functions are as follows:

• public void init() : Initialization function called only once by the browser.
• public void start() : Method called after init() and occupies code to start processing. If the user leaves the page and gives without killing the current browser session, the start () function is invoked without being preceded by init ().
• public void stop() : Stops all processing which started by start () method Done if user moves off page.
• public void destroy() : Called if current browser session is being ended. Frees all resources used by the applet.
