Creating Objects within While Loops

[Rocketz]

I'm trying to get UDP packets and store them in an ArrayList<DatagramPacket> within a while loop. However I feel like I'm adding a reference to a packet so that every object in the array just points to the last packet received. Here's what I'm working with:


DatagramPacket receivedPacket = null;

While (!finished) {
receivedPacket = new DatagramPacket(buf, buf.length);
socket.receive(receivedPacket); //socket is a DatagramSocket and this method changes the buffer within receivedPacket to contain the correct data from the current incoming packet.
packets.add(receivedPacket); //packets is an ArrayList<DatagramPacket>
}

When I then try to use the DatagramPackets that should be in the array, they're all the same. I check using syso's to make sure they're not the same before they're added.

I feel like an idiot that I can't figure this out after years of Java. Please help me.

My problem is that all instances of receivedPacket pointed to the same buffer which was created outside the while loop. Please close this thread.
