Please use code tags, if you wish us to go through the code. Also I hope you have indented the code correctly, because honestly I do not think any one will dare try to go through such a big file, especially if it is not presentable.
To use code tags, all you have to do is place the content inside, [code=java] and [/code] tags. Also please be kind enough to mention what is going wrong in your code, is it a compilation error or a runtime problem, and paste us the actual output which the compiler or the JRE is throwing up at you.
