In addition to displaying information in its window, an applet can also output a message to the status window of the browser or applet viewer on which it is running.

void showStatus(String msg)

The status window is a good place to give the user feedback about what is occurring in the applet, suggest options, or possibly report some types of errors. The status window also makes an excellent debugging aid, because it gives you an easy way to output information about your applet.
The following applet demonstrates showStatus( ):
