Changing x-value while holding key down

[earni23]

Hi
How do I increase the x-value by 20/sec while holding down the upper-key? If I have been holding the upper-key down for 5 sec the x-value should be 100 if initial x-value is 0.

By implementing the KeyListener interface or extending the KeyAdapter.
I think the keyPressed event fires until it reaches the keyReleased, and if it doesn't continually fire it doesn't matter since you can simply use KeyPressed as a start, and keyReleased as an end. Tie that in with a variable to listen to them, or using a thread and it can constantly update the variable for you.
