Local Inner Program in Java [Example]

Local Inner Program in Java

The LocalInner program is a minimal window program. The LocalInner constructor declares a local inner class named WindowHandler, which is used to handle the WindowEvent that is generated when the user attempts to close the window.
The WindowHandler class is a small class that is created and used within the scope that it is needed.
