Hi,
For the exam, do we need to know the exception hierarchy? I mean which are all the sub classes of RuntimeExceptions and which are not.
For some of the mock exam questions, i need to go and look in Java Api, to know the exception hierarchy (Mostly IOException etc.)
Thanks,
Narasimha.

It would be helpful to know a few of the more common exception types, such as IOException, NullPointerException, ArithmeticException, etc.
More importantly, though, you should understand the relationship between Throwable, Exception, RuntimeException, and Error.
 
It is sorta covered in the JavaRanch Style Guide.
