Problems with Java timer class.

[Energize]

I'm trying to use the timer class to repeat an action after a fixed amount of time, but I can't even get it to print the message once, as I keep getting the error. "exception in thread "Timer-0" java.lang.IllegalStateException: Task already scheduled or cancelled

That works, but it only executes the method once instead of repeating it.

It probably increments once as you have a call to dispensepetrol() at the end of your constructor.

Ah right, thats how I was testing whether the method works or not. I'll try it by calling the method via another method.
