//服务器端：

public class ChatServer {

public static void main(String[] args) {

}

public void start() {
try {

start = true;
int num = 0;
while (start) {
num ++;
s = ss.accept();
System.out.println("a client connet! " + num);
Client c = new Client(s,num);
new Thread(c).start();
clients.add(c);
}
ss.close();
} catch (Exception e) {
e.printStackTrace();
}
}

private class Client implements Runnable {
private Socket s = null;
private DataInputStream dis = null;
private DataOutputStream dos = null;
private int num = 0;
public Client(Socket s,int num) {
this.s = s;
this.num = num;
try {
dis = new DataInputStream(s.getInputStream());

} catch (IOException e) {

}

public void send(String str) {
try {
dos.writeUTF(str);
} catch (IOException e) {
clients.remove(this);
}
}
@Override
public void run() {
try {

while (!((str = dis.readUTF()).equals("exit"))) {
System.out.println("Form Client " + num + ": " + str);
for(int i=0; i<clients.size(); i++) {

c.send("Form Client " + num + ": " +str);
}
}
System.out.println("a client stoped!——" + num);

private class ChatMontions implements ActionListener {

@Override

}
}

private class Server implements Runnable {
@Override
public void run() {
try {
while (isRun) {
String str = dis.readUTF();
ta.setText(ta.getText() + "\n" + str);
}
} catch(EOFException e) {
System.out.println("结束！！");
}catch(IOException e) {
e.printStackTrace();
}
}
}
}

这是最简单的聊天程序，功能也很少，代码一共才200多一点。先启动服务器，再启动多个客户端，这个原理我想不用解释了吧，哦，注释我就不帮你写了，都这么晚了，我该看球了。呵呵
