各位大神请教一个建立简单聊天室问题，跪求指教！！！！
服务器程序

import javax.swing.*;
import java.io.*;
import java.net.*;
import java.awt.event.*;
import java.awt.*;
import java.util.concurrent.*;



public class Server {
JTextField servertxtf;
static JTextArea servertxta;

frame.add(servertxtf,BorderLayout.NORTH);
frame.add(servertxta,BorderLayout.CENTER);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setVisible(true);
}

ActionListener actionlistener=new ActionListener(){
public void actionPerformed(ActionEvent e){
if(socket==null){
servertxta.append("System：还未与客户建立连接");
}else{
servertxta.append("Server:"+servertxtf.getText()+"\n");
System.out.println(servertxtf.getText());
write.print(servertxtf.getText());
write.flush();
System.out.println("fuwuqi");
servertxtf.setText("");
}
}
};

}catch(IOException io){
System.out.println("接收信息出错");
break;
}
}
}
}

public static void main(String[]args){
new Server();

try{

exec.execute(new serverthread(clientNo));
}
}catch(IOException io){
System.out.println("建立服务其出错");
}finally{
try{
read.close();
write.close();
socket.close();
server.close();
}catch(IOException io){
System.out.println("未正常关闭");
}
}
}

}



客户端程序

import java.awt.*;
import javax.swing.*;
import java.io.*;
import java.net.*;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;

public class Client{
JTextField clienttxtf;
static JTextArea clienttxta;
static BufferedReader read;
static PrintWriter write;
static Socket socket;

public Client(){
clienttxtf=new JTextField(100);
clienttxtf.addActionListener(actionlistener);
clienttxta=new JTextArea();
JFrame frame=new JFrame("Client");
frame.add(clienttxtf,BorderLayout.NORTH);
frame.add(clienttxta,BorderLayout.CENTER);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setVisible(true);
}


ActionListener actionlistener=new ActionListener(){
public void actionPerformed(ActionEvent e){
if(socket==null){
clienttxta.append("System：还未与服务器建立连接");
}else{
clienttxta.append("client:"+clienttxtf.getText()+"\n");
write.print(clienttxtf.getText());
write.flush();
clienttxtf.setText("");
}
}
};

static class clientthread implements Runnable{
public void run(){
try{
read=new BufferedReader(new InputStreamReader(socket.getInputStream()));

while(true){
clienttxta.append("Server"+":"+read.readLine().toString()+"\n");
}
}catch(IOException io){
System.out.println("接收信息出错");
}
}
}



public static void main(String[]args){
new Client();
try{
socket=new Socket("localhost",8080);
write=new PrintWriter(socket.getOutputStream(),true);
new Thread(new clientthread()).start();
}catch(IOException io){
System.out.println("建立客户端出错");
}finally{
}
}
}


为什么我这样写的话程序不能实现互动？即在服务器端输入字符串只能在服务器的窗口中显示不能在客户端程序端口显示，在客户端输入字符串也一样，请问各位大神这是为什么？为什么服务器与客户端不能实现数据的传递？跪求答案啊，拜托拜托啊，大神们！！！！！！！！！！！！！

[解决办法]

BufferedReader 是在接收到"\r\n"(回车换行），才能读入一行的。接收不到，就阻塞着。
所以把客户端的write语句改一下：

Java code

write.print(clienttxtf.getText()+"\r\n");
