Non-blocking sockets?

[fishfry]

I need to write a batch program that listens for commands on a socket
.... in other words the main loop is

check socket for special command
handle request if present
else do next iteration of normal batch processing.

On a Unix system in C or Perl I'd use select() with a non-blocking
socket.

Can I do the equivalent in Java?

Or if not, would I listen for socket requests in a separate thread? That
seems like a Java-ish way to do it.

Read about java.nio.* (Selector, SelectionKey, SelectionChannel, ...)

But I would simply use a separate thread or non-blocking IO with sleep
(similiar to select()'s impl on non-SMP sys)
