Secs 31.6
Some of These are in Applet and some in parent (in particular Component)
public void init() is called ONCE and ONCE only when the applet is loaded or reloaded. Set initial parameters etc. here.
public void destroy() is what you do when Applet is entirely finished and you need to clean up stray threads or connections to be closed.
public void start() is called whenever the applet is started which can happen several times during an applet's life-cycle as it starts each time you revisit a page
public void stop() is called when we temporarily leave Applet to visit another page. A wise move would be to suspend running of Threads to save system resources.
