java.io.StreamCorruptedException

Question

你好我已经搜索了很多关于这个错误，但是还没找到答案。 当我尝试发送一个对象并接收我之前发送给服务器的对象时，我不断收到此错误。我想在我的客户端类中做所有这些。我找到了一些答案，说你必须在写（）对象之后刷新（）你的objectOutputStream，以使objectInputStream工作。

public void createAndListenSocket（）抛出ClassNotFoundException {

    //sending part
    try {
        Socket = new DatagramSocket();
        InetAddress IPAddress = InetAddress.getByName("localhost");
        byte[] incomingData = new byte[1024];
        Triangle student = new Triangle(1, 2, 45);
        ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
        ObjectOutputStream os = new ObjectOutputStream(outputStream);
        os.writeObject(student);
        os.flush();
        byte[] data = outputStream.toByteArray();
        DatagramPacket sendPacket = new DatagramPacket(data, data.length, IPAddress, 9876);
        Socket.send(sendPacket);
        System.out.println("Message sent from client");

      //receive part
           while (true)  {
               DatagramPacket incomingPacket = new DatagramPacket(incomingData, incomingData.length);
            Socket.receive(incomingPacket);
            byte[] datareceived = incomingPacket.getData();
            ByteArrayInputStream in = new ByteArrayInputStream(datareceived);
             ObjectInputStream is = new ObjectInputStream(in);
            receivedfromServer = (Triangle) is.readObject();
            reply = "Triangle received from the server is:" + " "+receivedfromServer.theta;
            Thread.sleep(2000);
           }
      }
    catch (UnknownHostException e) {
        e.printStackTrace();
    } catch (SocketException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (InterruptedException e) {
        e.printStackTrace();
    }

}
