Method Detail

main

public static void main(String[] args)

Description copied from class: EchoServer

Supply a port number as a command-line argument. Otherwise port 8088 will be used.

handleConnection

public void handleConnection(Socket server)

The new version of handleConnection starts a thread. This new thread will call back to the old version of handleConnection, resulting in the same server behavior in a multithreaded version. The thread stores the Socket instance since run doesn't take any arguments, and since storing the socket in an instance variable risks having it overwritten if the next thread starts before the run method gets a chance to copy the socket reference.
