Thread和Socket问题，通过TCP将多个线程通信，现在需要完成的是一个窗口发其它的窗口都能收到，请高手帮忙看看哪里出错了
Client端：
import java.awt.*;
import java.io.*;
import java.awt.event.*;
import java.net.*;
public class ChatClient extends Frame {
TextField tf = new TextField();
TextArea ta = new TextArea();
Socket socket;
DataOutputStream dos = null;
DataInputStream dis = null;
public static void main(String[] args) {
new ChatClient().launchFrame();
}
public void launchFrame() {
add(tf, BorderLayout.SOUTH);
add(ta, BorderLayout.NORTH);
setLocation(200, 200);
setSize(400, 300);
pack();
addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent arg0) {
disconnected();
System.exit(0);
}
});
connected();
new Thread(new ReceThread()).start();
tf.addActionListener(new Monitor());
setVisible(true);
}
private class Monitor implements ActionListener {
public void actionPerformed(ActionEvent e) {
ta.setText( tf.getText() + "\n");
try {
dos.writeUTF(tf.getText());
dos.flush();
} catch (IOException e1) {
e1.printStackTrace();
}
tf.setText(null);
}
}
private void connected() {
try {
socket = new Socket("127.0.0.1", 8888);
dos = new DataOutputStream(socket.getOutputStream());
dis = new DataInputStream(socket.getInputStream());
} catch (UnknownHostException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
private void disconnected(){
try {
socket.close();
dos.close();
} catch (IOException e) {
e.printStackTrace();
}
}
private class ReceThread implements Runnable{
public void run() {
try {
while(true){
String str = dis.readUTF();
ta.setText(ta.getText()+str);
}
} catch (IOException e) {
e.printStackTrace();
}
}
}
}
Server端：
import java.io.FilterInputStream;
import java.io.IOException;
import java.net.*;
import java.io.*;
import java.util.*;
public class ChatServer {
boolean start = false;
ServerSocket ss = null;
DataOutputStream dos = null;
ArrayList<Client> clients = new ArrayList<Client>();
public static void main(String[] args) {
new ChatServer();
}
public ChatServer() {
try {
ss = new ServerSocket(8888);
start = true;
} catch (IOException e1) {
e1.printStackTrace();
}
try {
start = true;
while (start) {
Socket s = ss.accept();
System.out.println("A socket connected");
Client c = new Client(s);
clients.add(c);
new Thread(c).start();
}
} catch (IOException e) {
e.printStackTrace();
} finally {
try {
ss.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
class Client implements Runnable {
private Socket s;
private DataInputStream dis;
private boolean connected = false;
public Client(Socket s) {
this.s = s;
connected = true;
try {
dis = new DataInputStream(s.getInputStream());
dos = new DataOutputStream(s.getOutputStream());
} catch (IOException e) {
e.printStackTrace();
}
}
public void send(String s) {
try {
dos.writeUTF(s);
} catch (IOException e) {
e.printStackTrace();
}
}
public void run() {
while (connected) {
try {
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("A socket is closed");
connected = false;
} catch (IOException e) {
e.printStackTrace();
try {
s.close();
dis.close();
} catch (IOException e1) {
e1.printStackTrace();
}
}
}
}
}
}
现在的问题是只有一个发能收到还是只有自己收到，收到的是把别人的也收到了，高手帮我看一下哪里出错了，顺便解释一下，谢了
[解决办法]
应该是你的dos定义的位置有问题，把dos的定义放到Client类里面来
