Answer 4

老兄速度好快呢 555555 我刚刚找到想说打上去.....:<
这个程序还好的 但是
我还是喜欢 os = new PrintWriter (ClientSocket.getOutputStream());
     is = new BufferedReader(new InputStreamReader(ClientSocket.getInputStream()));

Answer 5

呵呵，才快了一点点还有几个警告appendText最好改成append
还有readLine也不推荐使用

Answer 6

果然是高手 ，还有一个问题： 为什么客户端不能发送信息啊！！！！！！        if(e.getSource()==MyButton)
        {
            //try
            {
                os.print(textArea.getText());
                os.flush();
            }
        // catch(Exception e){}
        改成：        if(e.getSource()==MyButton)
        {
            try
            {
                os.print(textArea.getText());
                os.flush();
            }
         catch(Exception ex){}
        

Answer 7

if(e.getSource()==MyButton)
        {
            try
            {
                os.print(textArea.getText());
                os.flush();
            }
         catch(Exception ex){}
改成
        if(e.getSource()==MyButton)
        {
            try
            {
                os.print(textArea.getText());
                os.flush();
            }
         catch(Exception ex){System.out.println(ex);}
看看控制台有何错误信息，俺开始帮你调试时也出现你所说的问题，后来看到有错误，就知道了
好运

原理一样啊
给你一个例子(没用户界面的，是命令模式下的通信，自己可以改一下)
import java.net.*;
import java.io.*;
public class myServer{
 public static void main(String args[]){
  ServerSocket server;
  Socket sSocket;
  String hStr;
  InputStream fIn;
  OutputStream fOut;
  DataInputStream DIn;
  PrintStream hPS;
  try{
  server=new ServerSocket(4821);
  sSocket=server.accept();
  System.out.println("the server is on!");
  fIn=sSocket.getInputStream();
  fOut=sSocket.getOutputStream();
  DIn=new DataInputStream(fIn);
        hPS=new PrintStream(fOut);
  DataInputStream Userin=new DataInputStream(System.in);
  while(true){
  System.out.println("wait for the client...");
  hStr=DIn.readLine();
  System.out.println("client say: "+hStr);
  if(hStr.trim().equals("exit"))
  break;
  System.out.print("I say:");
  hStr=Userin.readLine();
  hPS.println(hStr);
  if(hStr.trim().equals("exit"))
  break;
  }
  DIn.close();
  hPS.close();
  fIn.close();
  fOut.close();
  sSocket.close();
        }catch(Exception e){
System.out.println("err:"+e);
                            }
        }
}
