我想为客户端和服务器建立套接字连接以显示文件列表。但是下面的代码不会从服务器获取任何输入或将输出提供给客户端。请帮忙。

服务器

package javaapplicationthread;

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.PrintWriter;



public class zs {
  public static int reads,red;  
    public static void main(String[] args) 
    { 
            int flg=0;

           try{while(true){ 
               ServerSocket serverSocket = new ServerSocket(1312);
           Socket clientSocket = serverSocket.accept();

                         BufferedReader bufferedReader;
       PrintWriter outk=new PrintWriter(clientSocket.getOutputStream(),true);

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

       String inputLine = bufferedReader.readLine();
       System.out.println("input is"+ inputLine);
       outk.write("abc");

         File inputFolder = new File(inputLine);
    System.out.println("control is being sent to traverse");
         traverse(inputFolder, "");

    }
           }            
       catch (IOException ex) {
                  System.out.println("my exception is"+ex)
            System.out.println(leftIndent + parentNode.getName());
        }

    }}
