Depends what you did with it. Did you create an appropriate HTML file naming this class in an applet tag, and open the HTML in a browser or the appletviewer application?

That's a Swing applet. How are you running that code, is it packaged properly, do you have a HTML web page with an applet tag, etc.? See Oracle's applet tutorial.

You should build the GUI in the Swing event dispatch thread, for example using SwingUtilities.invokeAndWait, as shown in this example.

Also, you do not need to call setVisible(true) for an applet.
