Checked and Unchecked Exceptions

[Rikesh Desai]

I am getting confused between Checked and Unchecked Exceptions.. especially in questions asking me -- Which of the following are checked exceptions?

Do we have to memorise all the checked and unchecked exceptions??

Can somebody provide pointers to some resource that can explain this topic.
Thanks in Advance.

All the classes subclass(direct/indirect) of RuntimeException class and RuntimeException class itself is unchecked exception.

There are a limited number of exception classes covered in the exam. Exceptions like IOException, InterruptedException etc which are actually related to other classes covered in the exam (IOException is thrown by some methods of File class, InterruptedException is thrown by some methods of Thread class and both File and Thread class are on the exam)...

All subclasses of RuntimeException and Error are unchecked exception. And only the exceptions that you encountered while studying for OCPJP would be worth looking into.

In the Exception part of the book, they are mentioned that, if you know the provided exceptions whether they are checked or unchecked, that's enough!
