im developing a multi-player card game that needs the clients to communicate with each other or a general server. i have never done this before so i need some direction or tutorial on how to achieve this.
so far i have created the local, single person version of the game...

Sun has a good tutorial on writing a client/server pair complete with code examples.

Great, I would suggest to continue with the local multi-player version of the game ( even when it is controlled by the same "terminal" )
From there you may explore RMI to invoke the methods remotely. It should be much more simpler than creating the multi-player version and add networking.
What RMI does is to abstract the network connectivity and allow you to simplify the execution of remote objects call ( that is, it simplifies having to write your own protocol with sockets )

RMI is more complex. You need to understand some concepts before starting with RMI, like extending Remote, RemoteExceptions, etc. And also, running applications powered by RMI require some steps, such as starting rmiregistry, and setting a policies file.
If you are a beginner, start with simple sockets first. They are easier to understand, but somewhat long to code. RMI is easier to code, but somewhat tough to understand.
For Sockets:
TCP Sockets
UDP and Datagrams
For RMI:
Simple tutorial to RMI - Really helped me start
