paint() is called automatically when the applet decides that it needs to update itself. When paint() is called, a handle to a Graphics object that represents the surface on which you can paint is passed into the method.
Case Study: Applet1.java
To run an applet, you must place it into a Web page and view the page
inside a Java-enabled Web browser.
| init() | Called when the applet is first created to perform first-time initialization of applet |
| start() | Called every time the applet moves into sight on the Web browser to allow the applet to start |
| stop() | Called every time the applet moves out of sight on the Web browser to allow the applet to shut off expensive operations. Alse called before destory() |
| destory() | Called when the applet is being unloaded from the page to perform final release of resources when the applet is no longer used |
