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.
