Hi everyone,

I just had a simple question for a java person.  I recently made a graphical java application named prog.java.  after i compile it, wham! 15 classes appear, named prog.class, prog$1.class, ..., prog$14.class.  

What's that all about?  If anyone has seen a good source on the net explaining this, i would love to see a link.  

Thanks so much,
Jennifer.

Please comment your comments. thanks!

All the $x.class are inner classes.
i.e

if you have the class like

public class A
{
 //..
 class b
 {
  //..
 }
}
If you compile the class you will get A.class & A$b.class. It means class b is an inner class for class A.

In your GUI program you may be used Listener inner classes.

For more detail goto http://java.sun.com/products/jdk/1.1/docs/guide/innerclasses/.
