Java : ObjectInputStream, 3 messages sent, only 2 received

Question

Welcome to the fabulous world of networks. I discovered my passion. :) However I have a very strange behavior in my app, and I would need your help to solve this one.

I made a simple server-client app. The sending Thread :

new Thread(new Runnable() {
    public void run() {
        try {
            ObjectOutputStream objectOutputStream = new ObjectOutputStream(new BufferedOutputStream(socket.getOutputStream()));
            objectOutputStream.writeObject(message);
            objectOutputStream.flush();

        } catch (Exception exception) {
            exception.printStackTrace();
        }
    }
}).start();

The receiving Thread :

new Thread(new Runnable() {
    public void run() {
        try {
            while (!Thread.currentThread().isInterrupted()) {
                ObjectInputStream objectInputStream = new ObjectInputStream(new BufferedInputStream(socket.getInputStream()));
                Message message = (Message) objectInputStream.readObject();
                Log.i("DEBUG", message);
            }
        } catch (Exception exception) {
            try {
                socket.close();
            } catch (Exception exception) {
                exception.printStackTrace();
            }
        }
    }
}).start();

It works just fine, however if I send simultaneously 3 messages , my receiving thread only receives the 2 first ones . It does not matter if I change the order. The third is always lost.

I think it's a buffer size problem. How can I deal with that? Thank you. :)

Answer 1

BufferedReader buffers the input, just as the name says. This means that it reads from the input source into a buffer before passing it onto you. The buffer size here refers to the number of bytes it buffers.

ObjectInputStream objectInputStream = new ObjectInputStream(new BufferedInputStream(socket.getInputStream(), size));

you can use size of BufferedInputStream and the reading of the buffer is slow so send the data with some delay `
