Java: use NIO with System.in [duplicate]

This question already has answers here: 开发者_运维知识库 How to get SelectableChannel from an InputStream? (2 answers) Closed 6 years ago.

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.

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

http://www.javafaq.nu/java-example-code-346.html

and in particular:

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