sorry it's not from javaBeat,it's from some mock I could'nt remember as I'm randomly doing from different materials.
Please be real careful here. The JavaRanch seems to be getting a rash of "source quotes" which are intentional done to hide the real source. (generally due to copyright issues).
I'm not saying that it is true in your case, but we have deleted whole groups of questions from a single poster, in the past, because of this. Please help the ranch, and your fellow posters, by keeping track of the sources.
