DataInputStream over DatagramSocket

Question

I have wrote a generic program that can accept data from DataInputStream. But recently I was trying to receive data from UDP using DatagramSocket. I have searched a lot, but I could nor fina a way to manipulate the incoming data from DatagramSocket to DataInputStream. Logically, since both are incoming data, there should be a way to integrate these two objects right? Am I wrong?

After getting answered from EJP I am right now using like this am i right?

byte[] buffer = new byte[2048];
DatagramPacket packet = new DatagramPacket(buffer, buffer.length);
DataInputStream dis = new DataInputStream(new ByteArrayInputStream(packet.getData(), packet.getOffset(), packet.getLength()));
While(true){
    dsocket.receive(packet);
    dis = new DataInputStream(new ByteArrayInputStream(packet.getData(), packet.getOffset(), packet.getLength()));
    reader = new MAVLinkReader(dis,MAVLinkMessage.MAVPROT_PACKET_START_V10);
    mesg = reader.getNextMessage();
    while (mesg != null) {...do stuff...}
}

Now what i feel is that since the reader is initialized to new dis each time the previously remaining bytes in dis becomes vanished.

Answer 1

Easy.

DataInputStream din = new DataInputStream(new ByteArrayInputStream(packet.getData(), packet.getOffset(), packet.getLength());

where packet is a DatagramPacket .
