The Life Cycle of an Applet

The Life Cycle of an Applet :

Loading the Applet

When an applet is loaded, here's what happens:

* An instance of the applet's controlling class (an Applet subclass) is created.
* The applet initializes itself.
* The applet starts running.

Leaving and Returning to the Applet's Page

When the user leaves the page -- for example, to go to another page -- the applet has the option of stopping itself. When the user returns to the page, the applet can start itself again. The same sequence occurs when the user iconifies and then reopens the window that contains the applet. (Other terms used instead of iconify are minaturize, minimize, and close.)

Reloading the Applet
Some browsers let the user reload applets, which consists of unloading the applet and then loading it again. Before an applet is unloaded, it's given the chance to stop itself and then to perform a final cleanup, so that the applet can release any resources it holds. After that, the applet is unloaded and then loaded again.

Quitting the Browser

When the user quits the browser (or whatever application is displaying the applet), the applet has the chance to stop itself and do final cleanup before the browser exits.
An applet can react to major events in the following ways:
1. It can initialize itself.
2. It can start running.
3. It can stop running.
4. It can perform a final cleanup, in preparation for being unloaded.
