上为Server

package com.liu.client;

import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.PrintWriter;
import java.net.Socket;
import java.net.UnknownHostException;

import javax.swing.*;

public class Myclient extends JFrame implements ActionListener{

	/**
	 * 
	 */
 
	JTextArea jta=null;
	JTextField jtf=null;
	JButton jb=null;
	JPanel jp=null;
	JScrollPane jsp=null;
	PrintWriter pw=null;
	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub

		Myclient myclient=new Myclient ();
	}
	public Myclient()  
	{
		jta=new JTextArea();
		jtf=new JTextField(20);
		jb=new JButton("Send");
		jb.addActionListener(this);
		jp=new JPanel();
		jsp=new JScrollPane(jta);
		jp.add(jtf);
		jp.add(jb);
		
		this.add(jsp,"Center");
		this.add(jp,"South");
		this.setTitle("Client");
		this.setSize(400,300);
		this.setVisible(true);
		
		try {
			Socket s=new Socket("127.0.0.1",9999);
			
			
			InputStreamReader isr=new InputStreamReader(s.getInputStream());
			BufferedReader br=new BufferedReader(isr);
			 pw=new PrintWriter(s.getOutputStream(),true);
			 
			 
			while(true)
			{
				System.out.println("Input what you say to server");
			    String info=br.readLine();
			    jta.append("Server to client:   "+info+"\r\n");
			    
			    
			    
			}
		} catch (UnknownHostException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
	@Override
	public void actionPerformed(ActionEvent e) {
		// TODO Auto-generated method stub
		if(e.getSource()==jb)
		{
			String info=jtf.getText();
			jta.append("Client to Server:   "+info+"\r\n");
			pw.println(info);
			jtf.setText("");
		}
	}
 

}

为Client
