This is Not an Applet. I think you need to check out the Life cycle of an Applet Here:

http://docs.oracle.com/javase/tutorial/deployment/applet/lifeCycle.html

回答2:

This class is not launching as an applet as it does not extend JApplet or Applet.

Even when this is fixed, nothing will appear in the applet client. Applets do not call the main method but rather init. Also don't create a new Frame for applet components - add them to the applet container itself.

Rather than using the old heavyweight AWT, use lightweight Swing. Also look at Java Web Start for deployment.
