求助 谁来帮我看一下这个关于套接字的程序
我想写一个类似于qq聊天窗口的程序,目前这个只是写了一个单方向的从服务器的窗口输入文字然后再客户端的控制台上可以看到,可是不知道为什么不能实现通信还有希望可以告送我怎么样可以方便的实现从服务器的Textfield中输入文字能在客户端的TextArea上看到 
程序代码：import javax.swing.JFrame;
import javax.swing.JPanel;

TextField textfield=new TextField(30);
JButton button=new JButton("发送");
ServerChat se=new ServerChat();
//private JList chat=new JList();
//private LinkedList<String> content=new LinkedList<String>();
TextArea textcontent=new TextArea(10,10);
private final int NUM=15;
public void init()
{
createframe();
se.link();
button.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent evt)
{
se.setL(textfield.getText());
se.send(se.list.get(0));
textcontent.setText("你对"+"说:"+textfield.getText()+"\n");
textfield.setText("");
}
});
textfield.setText("");
System.out.println("se.link()");
