Java TCP socket stream communication

Hello all,

Ive been giving a college assignment in which we must use swing GUI and TCP sockets to develop a client/server network in which the client can send messages (of type object, not string) over the network to the server which will then be rendered on all logged on client GUIs. My question is what is the best way for the server to display the messages on client GUIs, is it to use the drawString() method? Im not sure about my options on how to render the received messages onto the client GUIs and so would like some opinions/discussion.

Thanks
