Check If Java Interface Method Is Populated -

i have interface implemented next method: public void shutdown() quite few of classes implement method not utilize it. there way check if body of implementation has content in it?

i suppose add together boolean check, i'd avoid additional overhead.

in subclass, can throw java.lang.unsupportedoperationexception in shutdown() if there no implementation.

your calling class need grab exception you'll know class doesn't implement method.
