If you haven't yet downloaded and installed the documentation set for 
your JDK, it would be a good idea to do so. 

The documentation set lists the Exception(s) that are thrown by all the 
methods in library classes: you'll find that a lot more useful than a 
simple list of common exceptions. It also documents all Exceptions. This  
tells you which package an Exception belongs to, which Exception it is a 
subclass of and describes any additional methods it implements.

What do you mean by "debug them"?

You should learn about checked and unchecked exception and the
difference between them. Consider the following examples:

FileNotFoundException (checked)
ArrayIndexOutOfBoundsException (unchecked)

If by debugging an exception you mean to find its cause? Well, each
exception has a stack trace and a message attached. That should tell you
what happened, and where it happened.

Not every exception needs debugging. A FileNotFoundException is
perfectly normal, if one tries to open a file that does not exist.


Regards,
  Sven

Start with:

http://docs.oracle.com/javase/7/docs/api/java/lang/Exception.html

and drill down through subclasses and their subclasses.

One thing I love about having a website, is that when I complain about
something, I only have to do it once. It saves me endless hours of 
grumbling.

Hello,

You could try ExceptionBuddy Professional Vers 2.0.    You should avoid 
version 1.0.
