用JAVA开发一个简单的聊天软件

给个简单的客户端的例子，lz对比自己的码看看有什么出入 （注意：ClientHandler是inner class）package chap15;import java.io.*;import java.net.*;import java.util.*;public class VerySimpleChatServer{ArrayList clientOutputStreams;public class ClientHandler implements Runnable {BufferedReader reader;Socket sock;public ClientHandler(Socket clientSOcket) {try {sock = clientSOcket;InputStreamReader isReader = new InputStreamReader(sock.getInputStream());reader = new BufferedReader(isReader);} catch (Exception ex) { ex.printStackTrace(); }}public void run() {String message;try {while ((message = reader.readLine()) != null) {System.out.println(＂read ＂ + message);tellEveryone(message);}} catch (Exception ex) { ex.printStackTrace(); }}}public static void main(String[] args) {new VerySimpleChatServer().go();}public void go() {clientOutputStreams = new ArrayList();try {ServerSocket serverSock = new ServerSocket(5000);while(true) {Socket clientSocket = serverSock.accept();PrintWriter writer = new PrintWriter(clientSocket.getOutputStream());clientOutputStreams.add(writer);Thread t = new Thread(new ClientHandler(clientSocket));t.start();System.out.println(＂got a connection＂);}} catch (Exception ex) { ex.printStackTrace(); }}public void tellEveryone(String message) {Iterator it = clientOutputStreams.iterator();while (it.hasNext()) {try {PrintWriter writer = (PrintWriter) it.next();writer.println(message);writer.flush();} catch (Exception ex) { ex.printStackTrace(); }}}}

求一JAVA 聊天小程序使用图形用户界面。

能实现一个聊天室中多人聊...
