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