public class Error extends Throwable
Error is a subclass of Throwable
that indicates serious problems that a reasonable application
should not try to catch. Most such errors are abnormal conditions.
The ThreadDeath error, though a "normal" condition,
is also a subclass of Error because most applications
should not try to catch it.
A method is not required to declare in its throws
clause any subclasses of Error that might be thrown
during the execution of the method but not caught, since these
errors are abnormal conditions that should never occur.
That is, Error and its subclasses are regarded as unchecked
exceptions for the purposes of compile-time checking of exceptions.
