public class ChatClient extends Frame {
Socket s = null;
DataOutputStream dos = null;
DataInputStream dis = null;
private boolean bConnected = false;

TextArea taContent = new TextArea();
Thread tRecv = new Thread(new RecvThread());
public static void main(String[] args){
new ChatClient().launchFrame();
}
public void launchFrame(){
setLocation(400,300);
this.setSize(300,300);
add(tfTxt,BorderLayout.SOUTH);
add(taContent,BorderLayout.NORTH);
pack();
this.addWindowListener(new WindowAdapter(){
@Override
public void windowClosing(WindowEvent e) {
disconnect();
System.exit(0);
/*}
public void disconnect(){
try {

s.close();
} catch (IOException e) {
// TODO Auto-generated catch block

}*/
}
});
tfTxt.addActionListener(new TFListener());

聊天是两个人的事,所以要运行两次 ChatClient.java 哦,亲!
三、聊天阶段显示:
