Select JTextField you want to apply your code to. Then navigate to Properties window (if it's not visible in your layout, go right click on component -> Properties). Choose Events tab and find keyTyped in that list. Pick the value from combo box on the right and click on it, NetBeans will generate method stub for you to put your code into.
The quieter you are, the more you are able to hear.
