Why do you expect us to decipher your code and answer a question with so little information?

This is a very simple and basic question - did you do a google search? The following returned About 8,060,000 results in 0.97 seconds :(
https://www.google.com/search?client...ort+in+java%3F

So what specifically is it that you need?
What specifically are the issues you are encountering?
What specifically have you done in an attempt to solve those challenges?

Your questions really read like homework/course work questions and those are not allowed on this site.
