<h2>
11.1 The basic applet</h2>

<hr WIDTH="100%">
<br>You inherit from class <b>Applet</b> and override the application methods.
<p>paint() is called automatically when the applet decides that it needs
to update itself.&nbsp; When paint() is called, a handle to a Graphics
object that represents the surface on which you can paint is passed into
the method.
<p>Case Study: <a href="case/Applet/Applet1.java">Applet1.java</a><applet code=Applet1 width=100 height=20 codebase=case/Applet></applet>
<p>To run an applet, you must place it into a Web page and view the page
inside a Java-enabled Web browser.
<br>
<hr WIDTH="100%">
<br>An applet has its life cycle like a <i>thread</i> does.

<td>Called when the applet is first created to perform first-time initialization
of applet</td>

<tr>

<tr>
<td>stop()</td>

<td>Called every time the applet moves out of sight on the Web browser
to allow the applet to shut off expensive operations.&nbsp; Alse called
before destory()</td>
