java socket full duplex

Question

Is it possible to have a server and a client with 1 socket connection and send data in both directions at the same time? I mean both the server and the client reads and writes on the same time (2 threads in each process)

Edit: I need "true" two-way communications and not the request / response kind of communication. Both the client and the server must be able to write at the same time.

Edit2: God Dame! It works. Silly me I had a deadlock between client/server because of a write in the reader thread! :) Thanks

Answer 1

Yes, it seems use Threads each for sending and receiving on both sides. So one socket connection can do that.

Answer 2

TCP连接是一个全双工字节流 ，所以是的，您可以同时读取和写入同一个套接字，但您当然不必使用线程进行双向通信。
