Cannot refer to a non-final variable inside an inner class defined in a different method

Question

Edited: I need to change the values of several variables as they run several times thorugh a timer. I need to keep updating the values with every iteration through the timer

Answer 1

Because it's confusing if the variable isn't final, as the changes to it won't be picked up in the anonymous class.

Just make the variables 'price' and 'lastPrice' final.

-- Edit

Oops, and you'll also need to not assign to them, obviously, in your function. You'll need new local variables. Anyway, I suspect someone has given you a better answer by now.
