嗨，我是java的新手，我被困在这里，已经有一段时间了，我可以继续前进;我已经为聊天系统创建了一个GUI界面（虽然非常粗糙，因为我使用过java帮助文件，而且我之前从未做过很多）。但我有另一个代码，它独立，没有任何GUI，所有输出都在命令提示符。现在我想将所有输出附加到我创建的GUI。请帮助看看下面的代码，并建议方法和步骤，以帮助弄清楚...请这不是大学的任务，我是一个毕业生和工作所以我这样做，当我有时间，因为我相信知道java是一个很好的知识。谢谢你的时间。
这是我创建的聊天GUI类

Container container = getContentPane();
container.setLayout(new FlowLayout());
// create an ImageIcon

genMsg.setLineWrap(true);
container.add( new JScrollPane( genMsg ));
// create Friend List View

container.add(msgLabel);
// create Message Field
msgF = new JTextField(38);
msgF.setEnabled( true );
msgF.setText("");
msgF.requestFocus();
msgF.addActionListener(
new ActionListener()
{
// send message to client
public void actionPerformed( ActionEvent event )
{
// sendData( event.getActionCommand() );
}
} // end anonymous inner class
); // end call to addActionListener
container.add(msgF);
// create Send Button
sendBtn = new JButton ("Send");
container.add(sendBtn);
setVisible( true );
}
public static void main(String[] args)
{
MainView application = new MainView();
application.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
这是我要追加的聊天多线程系统。

任何建议都可以。是实现这一目标的步骤，使事情变得更容易的链接，代码片段...谢谢... 我想要一个关于如何将MultiThreadChatServer类的输出附加到MainView类中的textarea的示例
