Multiple keyboard responses/functions

Question

I am currently developing an app that is responsive to the viewer pressing keys on the keyboard. There are 36 different keys that will be pressed (a-z &0-9) when each key is pressed a specific colour will appear on screen, more than one key can be pressed at one time.

What is the code so that when you press the keys it triggers this?

see http://stackoverflow.com/questions/10876491/how-to-use-keylistener, you may also have a look at game libraries as there is a lot of keyboard interaction and display involved — Christophe Roussy, Mar 27 '14 at 15:19
On a side note, a keyboard usually has far more than 36 keys. — m0skit0, Mar 27 '14 at 15:20

You need to keep track of which key presses you care about (in boolean variables or an array). In keyPressed(), set the corresponding boolean to true. In keyReleased(), set it to false. Then just check against those booleans in your draw() function to display the correct color.
