Can you give me an example on how to create new exception and call/use that exception in my program? I try to googling but don't seem to find one. Thanks.

Looks like both #description and #defaultAction are instance-side methods of the classes under Exception.
So you'd define it as an instance-side method in your FileNotFound error.
