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.
