Is it possible to bind an action listener for keyboard events? E.g., I would like to write a program which computes something in the background, and when a key is pressed on the keyboard, the program executes a callback (a block of code).
Needless to say that the program is a command line program without any fancy GUI.
Any short snippet will be great 🙂

Take a look on the following discussions:
What's a good Java, curses-like, library for terminal applications?
How to determine if anything has been entered into the console window?
how can I detect arrow keys in java console not in GUI?
