hi there!
an exception is known as a checked exception if it is checked at compile time.
otherwise, it is known as unchecked exception like ArrayIndexOutOfBoundsException

Hi Junaid,
For more information on checked vs unchecked exceptions see JLS §11.2 and the Sun tutorial Handling Errors with Exceptions
I'm going to move your post to Certification Study as it's not realted to Mock Exam errors.
