JAVA代码编写一简单网络聊天程序

while(true){
this.sleep(100);
if(instr.ready()){
jTextArea1.append("服务器: "
+instr.readLine()+"\n");
}
}
}catch(Exception ex){
}
}
}
public void actionPerformed(ActionEvent e){
JPanel contentPane;
JLabel jLabel2 = new JLabel();
JTextField jTextField2 = new JTextField("4700");
JButton jButton1 = new JButton();
JLabel jLabel3 = new JLabel();
jLabel2.setText("端口号");
jLabel2.setFont(new java.awt.Font("宋体", 0, 14));
jTextField2.setBounds(new Rectangle(113, 27, 315, 24));
jButton1.setBounds(new Rectangle(440, 28, 73, 25));
jTextArea1.append("客户端已经连接到服务器\n");
MyThread t=new MyThread();
t.start();
}
}catch(Exception ex){
}
}
private void sendData(String s){//发送数据
try{
os= new PrintWriter(socket.getOutputStream());
JButton jButton2 = new JButton();
JScrollPane jScrollPane1 = new JScrollPane();
JTextArea jTextArea1 = new JTextArea();
BufferedReader instr =null;
Socket socket = null;
JLabel jLabel2 = new JLabel();
JTextField jTextField2 = new JTextField("4700");
JButton jButton1 = new JButton();
JLabel jLabel3 = new JLabel();
JTextField jTextField3 = new JTextField();
服务器端:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.io.*;
import .*;
public class Server extends JFrame implements ActionListener{
String s=this.jTextField3.getText().trim();
sendData(s);
}
}
private void connectServer(String ip,int port){//连接
try{
if(jButton1.getText().trim().equals("连接")){
要求：聊天室服务器、聊天室客户端；客户端之间可以聊天。
因为我是初级选手，想借此程序分析学习java，所以代码最好多一点注释...
分数有限，望大家不吝赐教!!问题补充：
需要图形用户界面哦，最好用swing组件
服务器端:采用多线程,可以向客户广播:当前聊天室人数,客户名称列表,客户进入离开提示;
客户端:可以设定昵称,性别,客户间可以私聊
ServerSocket server = null;
Socket socket = null;BufferedReader instr =null;PrintWriter os=null ;
//Construct the frame
