Java / Exception
When do you subclass an exception?
If the exception type is not represented by existing Exception in the Java platform, or if you need to provide more information to client code to treat it in a more precise manner, then you should create a custom exception.
Deciding whether a custom exception should be checked or unchecked depends entirely on the business case. However, as a rule of thumb; if the code using your exception can be expected to recover from it, then create a checked exception otherwise make it unchecked.
Also, you should inherit from the most specific Exception subclass that closely relates to the one you want to throw. If there is no such class, then choose Exception as the parent.
