br=new BufferedReader(new InputStreamReader(new StringReader(tar.getText())));

请问这句话有什么问题？

全部代码如下

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.io.*;
import java.net.*;
public class Server extends Thread implements ActionListener
{
private ServerSocket ss;
private Socket s;
private BufferedReader br;
private PrintWriter out;
private BufferedReader br_in;
private boolean isclose=false;

//服务器初始

JFrame f;
JTextArea ta=new JTextArea();
JTextArea tar=new JTextArea();
JButton b=new JButton("发送");

public Server()
{
f=new JFrame();
f.setTitle("C/S聊天工具");
Container c=f.getContentPane();
c.add("Center",ta);
c.add("Center",tar);
c.add("South",b);

f.setVisible(true);
b.addActionListener(this);
try
{

ss=new ServerSocket(8686);
ta.setText("服务器创建成功，等待用户加入！");
s=ss.accept();
ta.setText("用户已经加入，正在建立连接~");
br=new BufferedReader(new InputStreamReader(new StringReader(tar.getText())));
out=new PrintWriter(new StringReader(ta.setText()));
br_in=new BufferedReader(new InputStreamReader(new StringReader(tar.setText())));
ta.setText("连接成功");
}catch(Exception e){}

}
public void send()
{
try
{
ta.setText("请输入聊天信息");
String msg=br_in.readLine();
while(!msg.equals("byebye"))
{
out.print(msg);
out.flush();
msg=br_in.readLine();
}
out.println(msg);
out.flush();
this.isclose=true;
br.close();
br_in.close();
out.close();
s.close();

}catch(Exception e){}

}
public void revc()
{
while (isclose==false)
{
try
{
String msg=br.readLine();
ta.setText("收到信息"+msg);
}catch(Exception e){}
}
}






public static void main(String args[])
{
Server my=new Server();
my.start();
}

public void actionPerformed(ActionEvent e1)
{
Server my=new Server();
my.send();
}}

tar.getText()要判断一下是否为空值？

[scottwhb]

应该用Socket的
s.getInputStream();
s.getOutputStream();
