Java Socket client & server [duplicate]

问题

I tried the following code to send list of files and directories, from server to client. the server is receiving from client but i don't know whether server is not sending back the result or client is not accepting it.

Server side:

package without.thread;


import java.io.BufferedOutputStream;
import java.net.ServerSocket;
import java.net.Socket;
import java.io.BufferedReader;
import java.io.File;
import java.io.InputStreamReader;
import java.io.IOException;
import java.io.OutputStream;
import java.io.PrintWriter;
import static java.rmi.Naming.list;
import java.util.ArrayList;
import static java.util.Collections.list;
import java.util.logging.Level;
import java.util.logging.Logger;


public class SerTest {
  public static int reads,red;  
    public static void main(String[] args) 
    { 

          try
                  {
                      System.out.print("i m ready, call my client");
            ServerSocket serverSocket = new ServerSocket(18789);
                       while(true){ 
            Socket clientSocket = serverSocket.accept();
                        System.out.println(clientSocket+"1");
                       // outk=new PrintWriter(clientSocket.getOutputStream(),true); 

                         BufferedReader bufferedReader;
       bufferedReader = new BufferedReader(new InputStreamReader(clientSocket.getInputStream()));
                }

From what I can see you do readLine() on the client, while doing outqw.write() on the server. There is no end of line character in the string sent from server, so the client will never be able to finish the readLine. Do the outqw.println() or add "\n" to the end of whatever you're sending. That being said, it's very hard to navigate unformatted code with bunch of commented out stuff so the problem might be something else.
