New to Java

Hello,
I am relatively new to Java, though I am proficient in QBasic and understand object oriented programming. I was curious as to how I would go about creating something similar to an "inkey$" in Java. I checked the Java API, and it said something about a "KeyListener" class, though I didn't understand how to implement it very well. If someone could provide some sample code on using this KeyListener class, I would be very grateful.

Good day, and thanks in advance :)
