如何发送文件

我需要改变这个代码，以便它会在它目前只发送一个文件的时刻发送图像文件的目录的目录，我的主要目标是有它要求一个目录，然后送所有在该目录中的文件（图像文件）到服务器，然后我需要它来显示有多少数据被发送的代码，我现在拥有的是：如何发送文件

客户：

package sockets; 
import java.net.*; 
import java.io.*; 

public class Client { 

    public static void main (String [] args) throws IOException { 
     int filesize=1022386; 
     int bytesRead; 
     int currentTot = 0; 
     Socket socket = new Socket("127.0.0.1",6789); 
     byte [] bytearray = new byte [filesize]; 
     InputStream is = socket.getInputStream(); 
     FileOutputStream fos = new FileOutputStream("copy.txt"); 
     BufferedOutputStream bos = new BufferedOutputStream(fos); 
     bytesRead = is.read(bytearray,0,bytearray.length); 
     currentTot = bytesRead; 
     System.out.println("The Size of the data transferred is " + bytesRead + " Bytes"); 

     do { 
      bytesRead = 
       is.read(bytearray, currentTot, (bytearray.length-currentTot)); 
      if(bytesRead >= 0) currentTot += bytesRead; 
     } while(bytesRead > -1); 

     bos.write(bytearray, 0 , currentTot); 
     bos.flush(); 
     bos.close(); 
     socket.close(); 
     } 
}

服务器：

package sockets; 
import java.net.*; 
import java.io.*; 
public class Server { 


public static void main (String [] args) throws IOException {` 

      ServerSocket serverSocket = new ServerSocket(6789); 
       Socket socket = serverSocket.accept(); 
       System.out.println("Accepted connection : " + socket); 
       File transferFile = new File ("Orders.txt"); 
       byte [] bytearray = new byte [(int)transferFile.length()]; 
       FileInputStream fin = new FileInputStream(transferFile); 
       BufferedInputStream bin = new BufferedInputStream(fin); 
       bin.read(bytearray,0,bytearray.length); 
       OutputStream os = socket.getOutputStream(); 
       System.out.println("Sending Files..."); 
       os.write(bytearray,0,bytearray.length); 
       os.flush(); 
       socket.close(); 
       System.out.println("File transfer complete"); 
      } 
}

谢谢
