What is an applet?

John Zukowski

Basically, an applet is a Java class, extending from java.applet.Applet that runs in a Web browser, loaded from an APPLET tag in an HTML file. The browser then calls applet life-cycle methods like start(), stop(), init(), and destroy() as needed. There are security restrictions untrusted applets must abide by, like not being able to connect to anywhere besides the web server from which it came.
