Is UDP (in Java or otherwise) full duplex by default?

Question

I.e. am I able to read from and write to the same socket using two different threads, given that I'm doing all communication in the form of datagrams?

How does the code for this work? Is it fine to create one datagram socket, and use socket.receive as well as socket.send from two different threads? — Sam, Mar 11 '14 at 15:18

UDP, in the right circumstances, can be considered fully duplex, but by itself, it is not, whereas TCP, on the other hand, is always fully duplex.

UDP is a fire-and-forget, best-effort protocol, but the upper layers can use it in a fully duplex fashion.

TCP requires handshaking and other two-way communication.

UDP IS in fact fully duplex.

You can have a server listening from as well as writing to the same socket
