Question

求一个用java socket编写的聊天室程序，能运行的附带源码，有客户端和服务器端

急求啊，谢谢了

Answer 1

也不知道怎么说怎么用，我写的代码，很久了，用的是awt，感觉Java在应用程序上没前景所以就没在深入了……现在主攻J2ee，代码给你，你自己感觉吧
服务端：
import java.io.*;
import java.net.*;
import java.util.*;
public class ChatServer {
boolean started = false;
ServerSocket ss = null;
List<Client> clients = new ArrayList<Client>();
public static void main(String[] args) {
new ChatServer().start();
}
public void start() {
try {
ss = new ServerSocket(8888);
started = true;
} catch (BindException e) {
System.out.println("端口使用中....");
System.out.println("请关掉相关程序并重新运行服务器！");
System.exit(0);
} catch (IOException e) {
e.printStackTrace();
}
try {
while(started) {
Socket s = ss.accept();
Client c = new Client(s);
System.out.println("a client connected!");
new Thread(c).start();
clients.add(c);
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
ss.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}

class Client implements Runnable {
private Socket s;
private DataInputStream dis = null;
private DataOutputStream dos = null;
private boolean bConnected = false;

public Client(Socket s) {
this.s = s;
try {
dis = new DataInputStream(s.getInputStream());
dos = new DataOutputStream(s.getOutputStream());
bConnected = true;
} catch (IOException e) {
e.printStackTrace();
}
}

public void send(String str) {
try {
dos.writeUTF(str);
} catch (IOException e) {
e.printStackTrace();
}
}

public void run() {
try {
while(bConnected) {
String str = dis.readUTF();
System.out.println(str);
for(int i=0; i<clients.size(); i++) {
Client c = clients.get(i);
c.send(str);
}
}
} catch (EOFException e) {
System.out.println("Client closed!");
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
if(dis != null) dis.close();
if(dos != null) dos.close();
if(s != null) {
s.close();
//s = null;
}
} catch (IOException e1) {
e1.printStackTrace();
}
}
}

}
}
客户端，开两个就能聊了……
import java.awt.*;
import java.awt.event.*;
import java.io.*;
import java.net.*;

public class ChatClient extends Frame {
Socket s = null;
DataOutputStream dos = null;
DataInputStream dis = null;
private boolean bConnected = false;
TextField tfTxt = new TextField();
TextArea taContent = new TextArea();
Thread tRecv = new Thread(new RecvThread());
public static void main(String[] args) {
new ChatClient().launchFrame();
}

public void launchFrame() {
setLocation(400, 300);
this.setSize(300, 300);
add(tfTxt, BorderLayout.SOUTH);
add(taContent, BorderLayout.NORTH);
pack();
this.addWindowListener(new WindowAdapter() {

@Override
public void windowClosing(WindowEvent arg0) {
disconnect();
System.exit(0);
}

});
tfTxt.addActionListener(new TFListener());
setVisible(true);
connect();

tRecv.start();
}

public void connect() {
try {
s = new Socket("127.0.0.1", 8888);
dos = new DataOutputStream(s.getOutputStream());
dis = new DataInputStream(s.getInputStream());
System.out.println("connected!");
bConnected = true;
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}

}

public void disconnect() {
try {
dos.close();
dis.close();
s.close();
} catch (IOException e) {
e.printStackTrace();
}

}

private class TFListener implements ActionListener {

public void actionPerformed(ActionEvent e) {
String str = tfTxt.getText().trim();
tfTxt.setText("");

try {
dos.writeUTF(str);
dos.flush();
} catch (IOException e1) {
e1.printStackTrace();
}

}

}

private class RecvThread implements Runnable {

public void run() {
try {
while(bConnected) {
String str = dis.readUTF();

taContent.setText(taContent.getText() + str + '\n');
}
} catch (SocketException e) {
System.out.println("�˳��ˣ�bye!");
} catch (IOException e) {
e.printStackTrace();
}

}

}
}
