Doubt on using Threads / applets

[Pavan]

Hi,
Would like if someone gave a basic explanation of how
to use start(), init(), stop() methods in an applet.

Thanx
Pavan

get a copy of thinking in java from the web - its free and covers threads
very well.

Hello Pavan:

In an applet, these aren't really thread methods per se. Rather, they control
the life-cycle of the applet relative to the browser. You must include an
init() method as it is the entry point for the applet - much like the main
method in an application. start(), stop(), and destroy() are optional.
stop() is called whenever a user leaves the page with the applet on it.
start() is called whenever the user returns to the page. destroy() is called
when the browser is killed. These methods allow the developer to clean up
any resources while the user is going to another page or to re-allocate them
when the user returns.

As an example, suppose you have an applet that loops a sound file. You'd
probably start the sound playing in the init() method. You wouldn't want
the sound to keep playing when the user leaves the page, so you'd stop it
in the stop() and destroy() methods. Then, if you want the sound to start
when a user returns to the page, just start it again in the start() method.

HTH,
