java模拟聊天窗口怎么两个人聊天啊？

简单一点用session，复杂一点么，tomcat上面有聊天室的示例程序，用的长链接

我要一份用java网络编程写的点对点的两人聊天程序(TCP和UDP)?

Server端：

import java.io.*;

import java.net.*;

import java.applet.Applet;

public class TalkServer{

public static void main(String args[]) {

try{

ServerSocket server=null;

try{

server=new ServerSocket(4700);

}catch(Exception e) {

System.out.println("can not listen to:"+e);

}

Socket socket=null;

try{

socket=server.accept();

}catch(Exception e) {

System.out.println("Error."+e);

}

String line;

BufferedReader is=new BufferedReader(new InputStreamReader(socket.getInputStream()));

PrintWriter os=new PrintWriter(socket.getOutputStream());

BufferedReader sin=new BufferedReader(new InputStreamReader(System.in));

System.out.println("Client:"+is.readLine());

line=sin.readLine();

while(!line.equals("bye")){

os.println(line);

os.flush();

System.out.println("Server:"+line);

System.out.println("Client:"+is.readLine());

line=sin.readLine();

}

os.close();

is.close();

socket.close();

server.close();

}catch(Exception e){

System.out.println("Error:"+e);

}

}

}

Client端：

import java.io.*;

import java.net.*;

public class TalkClient {

public static void main(String args[]) {

try{

Socket socket=new Socket("127.0.0.1",4700);

BufferedReader sin=new BufferedReader(new InputStreamReader(System.in));

PrintWriter os=new PrintWriter(socket.getOutputStream());

BufferedReader is=new BufferedReader(new InputStreamReader(socket.getInputStream()));

String readline;

readline=sin.readLine(); //从系统标准输入读入一字符串

while(!readline.equals("bye")){

os.println(readline);

os.flush();

System.out.println("Client:"+readline);

System.out.println("Server:"+is.readLine());

readline=sin.readLine(); //从系统标准输入读入一字符串

}

os.close(); //关闭Socket输出流

is.close(); //关闭Socket输入流

socket.close(); //关闭Socket

}catch(Exception e) {

System.out.println("Error"+e); //出错，则打印出错信息

}

}

}

求java两人聊天室程序 有图形 源代码，请高手指教

package socketserver;

import socketserver.ReadThread;

import java.io.DataInputStream;

import java.io.IOException;

import javax.swing.JTextArea;

public class ReadThread extends Thread{

JTextArea ta;

DataInputStream dis;

public ReadThread(JTextArea t,DataInputStream d)

{

this.ta=t;

this.dis=d;

}

public void run(){

try{

while(true)

{

ta.append("对方说："+dis.readUTF());

ta.append("\n");

}

}

catch(IOException e)

{

System.out.println("连接中断!");

}

}

看不懂了在问我

用java做一个两个人之间的聊天软件

2个类搞定,一个socket,一个serversocket，通过ip和端口连接后用输入输出流对接，原理大概是这样

以前学Java看马士兵视频时有这么个例子，讲的不错，楼主可以搜搜马士兵聊天室的例子
