Java-同一TCP IP的不同套接字

Question

I want to create different thread for read and write method by using socket. I wonder should I use different socket or same socket to share for both thread?

Answer 1

If you're reading and writing to and from the same device/object, i'd use the same thread. This way you don't have it trying to read something when you haven't written to it yet. Doing multiple threads might cause a multitude of errors if you're not careful, such as nulls.

Answer 2

You can use the same socket to both read and write. Of course one of the 2 endpoints must open a server socket. Then you can have 1 thread blocked waiting for input data while another thread could output data when needed

Answer 3

1. Create One socket object .

2. Use any nos of threads to access this object, but do keep enough care to make the write and read operations Thread-Safe .

3. Try using the ServerChannel and ServerSocketChannel from java.util.nio package, which is Asynchronous .
