我正在写一个客户端 - 服务器程序,我希望它发送一个图像.代码如下:

//RECEIVER
while(true){
  try{
            socket = server.accept();

            out = new ObjectOutputStream(socket.getOutputStream());
            out.flush();
            in = new ObjectInputStream(socket.getInputStream());

            System.out.println("Connected to "+PORTA+".");

            while(!socket.isClosed()){ 
                System.out.println("\nPrint the action");
                azione = reader.readLine();

           if(azione.equals("screenshot")){

                    out.writeObject("screenshot");
                    out.flush();
                    BufferedImage screenshot = ImageIO.read(in);

                    ImageIO.write(screenshot, "jpg", new File("screenshot.jpg"));
                }
  }catch(Exception ex){
            System.out.println("Not connected.\n");
  } 
}

和服务器:

while(true){ 
   try{
            socket = new Socket(INDIRIZZO, PORT);

            out = new ObjectOutputStream(socket.getOutputStream());
            out.flush();
            in = new ObjectInputStream(socket.getInputStream());

            while(!socket.isClosed()){
                try {
                  action = (String)in.readObject();
                  if(azione.equals("screenshot")){
                        BufferedImage screenshot = new Robot().createScreenCapture(new Rectangle(Toolkit.getDefaultToolkit().getScreenSize()));
                        ImageIO.write(screenshot, "jpg", out);
                    }catch(Exception …
