A Server Program – BankService

• BankService carries out the service
• Implements the Runnable interface
• Its run method will be executed in each thread that serves a client connection
• run gets a scanner and writer from the socket, then executes:

  public void doService() throws IOException
  {
     while (true)
     {
        if (!in.hasNext()) return;
        String command = in.next();
        if (command.equals("QUIT")) return;
        executeCommand(command);
     }
  }
