I was recently asked how to implement function call-back in JAVA. My answer was to use Observer/Observable interfaces.
Is this answer correct ? Is there a way to do it without using interfaces ?
Thanks for the input !

This forum walks a fine line. In this cause, while undoubtedly an interview question, I think it's more appropriate for a different forum, specifically, Java In General (Adv), so I'm moving it there.
