Java keyboard input parsing in a console app

Question

I\'ve just started messing around with JLine to parse character input in console mode. It seems to work well, but I\'m wondering:

Is there a nonblocking way in JLine

Answer 1

You seem to be on the right track.

I think the "right" way to do this is a worker thread that pours all the blocking I/O into a non-blocking queue. Hava a look at ConcurrentLinkedQueue from java.util.concurrent.

Answer 2

You can't use a console to get non-blocking input without native libraries.

You'll have to write a Swing app and write a KeyListener
