Amigo continuo com dúvida.
Ja ta quase tudo pronto, só falta esse detalhe de pegar da área de texto e enviar para o servidor, eu fiz usando o console e da blz.
No método run() e conectar() que está o pipino.
Já que uso evento do teclado, quando apertar <ENTER> e enviada a mensagem, ta dando erro.
Olha o código logo abaixo.
