As Kemal mentioned, state your problem clearly so that you could be helped..
1. what is 'the worksheet' question?..from the heading, it looks like you are reading an excel spreadsheet into a Java obj.
2. you just need to loop it through the worksheet rows, check if they are not nil, and then read the values...you might want to take a look at jxl.jar library.
3. what form of output are you expecting?
