Multithreading server /- client doesnt update need a little help

Question

I have three classes, one is my client called lobby, the second is my server, then my third is the server thread. Everything works but the client doesnt seem to update unless you type stuff in and hit enter or press send and that isbecause of the key and action listeners, how do i go about having to updating every 10 seconds or less..? I tried doing a while statement and of course it freezed it because its an infinite loop, tried making it a thread, not to good at that, i just need some advice on how to solve this problem, thanks.
