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.

My dout is .... The compiler checks the class of the reference type -not the object type -to see if you can call a method using that reference .
so what about the interfece reference type?
Same strategy for interface as well ( as with class)
