socket傳送檔案

我想傳送多個檔案
每當伺服器接收到使用者端傳送的傳送訊器再傳送
不過每次伺服器都會提早跳出迴圈
所以使用者端都會卡在迴圈裡
能有甚麼辦法?

伺服器

1. while (true) {
   
2.     data = buf.readLine();
   
3.     if (data.equals("print")) {
   
4.         printscreen();//截圖
   
5.         FileInputStream picStream = new FileInputStream(outFileName);
   
6.         OutputStream outStream = socket.getOutputStream();
   
7.         byte buff[] = new byte[1024];
   
8.         int len = 0;
   
9.         while ((len = picStream.read(buff)) > -1) {
   
10.             outStream.write(buff, 0, len);
    
11.         }
    
12. }

使用者端
因為使用者端視android，所以沒有while迴圈包覆

1. out.println("print");
   
2. InputStream inStream = CA.socket.getInputStream();
   
3. FileOutputStream outStream = new FileOutputStream(PATH);
   
4. byte buff[] = new byte[1024];
   
5. int len = 0;
   
6. while ((len = inStream.read(buff)) != -1 ) {
   
7.     outStream.write(buff, 0, len);
   
8. }
