Appendix A Concurrency II by Brett L. Schuchert This appendix supports and amplifies the Concurrency chapter on page 177. It is written as a series of independent topics and you can generally read them in any order. There is some duplication between sections to allow for such reading.

ServerSocket serverSocket = new ServerSocket(8009); while (keepProcessing) { try { Socket socket = serverSocket.accept(); process(socket); } catch (Exception e) { handle(e); } } 317
