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?

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);

You could create a Pipe and a custom thread to read from standard input and write to the pipe.

Once you have the Pipe you can then get the input channel.

How to get SelectableChannel from an InputStream?

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)
