java 聊天室代码?

前天帮人解决过,代码如下：public class iChat extends JFrame {

private JPanel jContentPane;

private JButton jButton1;

private JScrollPane jScrollPane1;

super();

initialize();

} private void initialize() {

jTextArea1 = getJTextArea1();

this.setContentPane(getJContentPane());

this.setTitle("聊天室");

setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); } private JPanel getJContentPane() {

if (jContentPane == null) {

jContentPane = new JPanel();

jContentPane.setBackground(Color.BLUE);//蓝色为JPanel .

jContentPane.setLayout(null);

jContentPane.add(getJButton1(), null);

jContentPane.add(getJScrollPane1(), null);

}

return jContentPane;

public void keyTyped(java.awt.event.KeyEvent e) {

if (e.getKeyChar() == KeyEvent.VK_ENTER) {

String date = new SimpleDateFormat(

"yyyy-MM-dd HH:mm:ss").format(Calendar

.getInstance().getTime());

jTextArea1.append(date + "\n");

jTextArea1.append(s);

});

} private JButton getJButton1() {

if (jButton1 == null) {

jButton1 = new JButton();

jButton1.setText("发送");

jButton1.addActionListener(new java.awt.event.ActionListener() {

public void actionPerformed(java.awt.event.ActionEvent e) {

String date = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss")

.format(Calendar.getInstance().getTime());

jTextArea1.append(s + "\n");

return jButton1;

private JScrollPane getJScrollPane1() {

if (jScrollPane1 == null) {

jScrollPane1 = new JScrollPane();

jScrollPane1.setViewportView(getJTextArea1());

return jScrollPane1;

} private JTextArea getJTextArea1() {

if (jTextArea1 == null) {

jTextArea1 = new JTextArea();

jTextArea1.setEditable(false);

jTextArea1.setLineWrap(true);

return jTextArea1;

} public static void main(String[] args) {

SwingUtilities.invokeLater(new Runnable() {

public void run() {

iChat thisClass = new iChat();

thisClass.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

thisClass.setVisible(true);

}}

你要的就是点对点通信,见以下例子：

①简单服务器端

/*

import java.net.*;

import java.io.*;

*/

ServerSocket server=null;

try {

server=new ServerSocket(%%1);

}catch(Exception e){

System.out.println("不能监听:"+e.toString());

Socket socket=null;

socket=server.accept();

catch(IOException e){

System.out.println("出错:"+e.toString());

}finally{

if(socket!=null){

socket.close();

server.close();

e.printStackTrace();

finally{

//import java.net.*;

String strIP = null;

try

{

strIP =InetAddress.getLocalHost().getHostAddress().toString();

catch(UnknownHostException e)

%%1=InetAddress.getLocalHost().getHostAddress();

EnumerationNetworkInterface netInterfaces = null;

netInterfaces = NetworkInterface.getNetworkInterfaces();

while (netInterfaces.hasMoreElements()) {

NetworkInterface ni = netInterfaces.nextElement();

System.out.println("DisplayName:" + ni.getDisplayName());

System.out.println("Name:" + ni.getName());

EnumerationInetAddress ips = ni.getInetAddresses();

while (ips.hasMoreElements()) {

System.out.println("IP:"

+ ips.nextElement().getHostAddress());

} catch (Exception e) {

@Override

ServerSocket server = null;

System.out.println("不能监听:" + e.toString());

Socket socket = null;

socket = server.accept();

BufferedReader req = new BufferedReader(new InputStreamReader(

socket.getInputStream()));

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

Debug.p(req.readLine());

os.println("Server");

os.flush();

os.close();

req.close();

} catch (IOException e) {

System.out.println("出错:" + e.toString());

} finally {

if (socket != null) {

t.start();

strIP = InetAddress.getLocalHost().getHostAddress().toString();

} catch (UnknownHostException e) {

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

BufferedReader br = new BufferedReader(new InputStreamReader(socket

.getInputStream()));

pw.println("Client");

pw.flush();

Debug.p(br.readLine());

pw.close();

br.close();
