Java sockets: DataOutputStream or OutputStream?

Question

I\'m still relatively new to sockets, and I haven\'t seen any information regarding this subject.

To write to a connected socket, you can either use

sock         


        

Answer 1

Use DataOutputStream if you need the extra APIs. If you don't, there is no point. But you should always wrap the socket's output stream in a BufferedOutputStream if you are doing small writes, and flush() when appropriate, i.e. before you read the socket for example.
