You have no idea what to do, right?
Well, to put it short:
Server
-create a ServerSocket on a desired port
-get a socket through accept()
-get outputsteram from it
-write word of the day to the stream
Client
-create a socket connecting to the server on the desired port
-get inputstraam from it
-read word of the day from the stream
If you are still having problems, read the docs and tuts more thoroughly.
