First of all post a proper SSCCE when asking a code. The reason your last question had 18 replies is because you didn't simplify the code or question.
Your question is about using a filter so there is absolutely no need to post 500 lines of code. All you need is a JFrame with a JTable and some data in the table. A SSCCE can be created in about 20-30 lines of code.
