Sharing Thread Data

I'm going through the java socket tutorial (http://java.sun.com/docs/books/tutorial/networking/sockets/clientServer.html) and implementing the multi-client server at the bottom of the page.

However, I'm trying to add a method to the main class that creates the threads, increment(), that can be called by any of the threads to increment a simple counter in the base class. How can I set this up so that any of the threads can call this method, which is a parent two classes above the thread classes?
