Esse exemplo foi desenvolvido no netbeans. É um socket servidor e cliente, que envia mensagens de um para o outro, lembra o msn.

A conexão é encerrada quando se digita TERMINATE. Para iniciar, coloque o numero da porta nos dois, e o endereço no cliente(localhost), pode ser endereço ip se for em maquinas diferentes.

Abaixo estão os dois codigos. Caso alguém melhorar mande para mim.
