public class Exception extends Throwable
Exception
and its subclasses are a form of Throwable
that indicates
conditions that a reasonable application might want to catch.
The class Exception
and any subclasses that are not also subclasses of
RuntimeException
are checked
exceptions. Checked exceptions need to be declared in a method or constructor's
throws
clause if they can be thrown by the execution of the method or constructor and
propagate outside the method or constructor boundary.
