Java methods throw exceptions that are subclasses of another exception that they also throw?

IOException, which it also throws. Syntactically, it would have been okay to just throw the more general (in this case, IO) exception and to omit the HttpException from the
Does listing more specific exceptions in the throws clause of a method beside a more general one accomplish anything?
