I’m a learner, so please be patient and clear. I am writing an echo client with Java sockets (DatagramSocket).

After the client sends a message to the echo server, the server deliberately sends 1-10 copies of the message back to simulate message duplication in UDP.

However, my code can only receive the first of those messages sent back, never the full number sent by the server. My receive code is like this:

socket.receive(receivePacket);

How would I put my client in a state where you can enter a string to echo, say “Hi”, it is then sent to the server, but can then receive all the replies? I am assuming that they all make it back to the client (I am testing this on my local machine so there will be no loss)

    Call socket.receive again to receive additional packets. Set a timeout to wait a reasonable amount of time before deciding the server has sent all its packets.
