how do you bypass the enter(/n) key in a program?

Hello,

I need a simple program that ask's to enter an integer from 0-9 without having to press the enter key. I just want to press the integer key and I want the program to read the key and store it in a variable. Please help me. I am not very proficient in Java. I need help!

If that's a console app you need the enter key, no other way. If it's a GUI you can add a DocumentListener or KeyListener.
