Java: use NIO with System.in

Question

Is it possible to use NIO with System.in?

I would like to somehow treat 'stdin' as a selectable channel. Has anyone found a way to do this?

hmmm... on second thought, for stdin there may be a solution. I found this reference:

and in particular:

SystemInPipe.java (class which encapsulates stdin as a selectable channel)

Answer 2

I don't know about a SelectableChannel, but you can convert an InputStream to a ReadableByteChannel with

using java.nio.channels.Channels;

...

ReadableByteChannel in = Channels.newChannel(System.in);
