Suggestions for allowing us to better be able to help you:

• Please edit your posted code above and wrap that code in [code][/code] tag. The first tag goes on top of the code block, and the second tag goes at the bottom of your post below the posted code block.
• Please ask an actual answerable question. You haven't yet explained what help you need exactly, what is wrong with your current code,... etc. The more you can tell us, the better we'll know what to do.
• Please edit your initial post and click on the "Go Advanced" button and change the title of your forum thread. This title is supposed to be short and informative, a summary of your problem. "Please help anyone please" is not very informative and doesn't tell us in a nutshell what is wrong.

Much luck!

Please go through the Java coding conventions and learn how to format your code for readability.

the app doesn't run at all

How, exactly, did you try to run it? Also, do you have the author's permission to reproduce the code on a public forum?
