What Is the Listener for Key Presses?

[KevinSimonson]

I'm familiar with how one writes code that is executed when the user
clicks or drags a mouse button. How does one write code that is
executed when the user presses a key on the keyboard? I'm not talking
about using the <Scanner> class to detect a string entered terminated
by the <return> key. I want my code to be executed when the user
presses a single key. I used to know how to do this, but I don't have
any existing code that does it any more, and I don't remember the
listener class/interface I need to use. Any pointers anyone can give
me on this would be greatly appreciated.

The standard listener is java.awt.KeyListener, but this is primarily
oriented towards GUI applications. If you want to listen for individual
keystrokes in a console-based applications, you will have to go with
some Java curses-based approach (such for "Java curses").
