This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
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. --Mark
