如何發送文件

我需要改變這個代碼，以便它會在它目前只發送一個文件的時刻發送圖像文件的目錄的目錄，我的主要目標是有它要求一個目錄，然後送所有在該目錄中的文件（圖像文件）到服務器，然後我需要它來顯示有多少數據被髮送的代碼，我現在擁有的是：如何發送文件

客戶：

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(); 
     } 
}

      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"); 
      } 
}
