First off, this is JAVA code, not javascript. You're in the wrong forum.
Second, did you have a question? Or did you just want to spam the forum with code without CODE-tags surrounding them? Learn to forum, please.

 

As I used to have as a signature here, Java is to JavaScript as Ham is to Hamburger.

... and yeah, without an actual question what was the point of this thread?
