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.
