ff.addWindowListener(new AppCloser()) problem

Zone: Java Standard Edition

Tags: Java

I am receiving an error "cannot find symbol AppCloser class". However if place the main method into the TestEventFrame class it works fine. How do I solve this problem?.

Your help is kindly appreciated.

Regards.
