Hello, everybody:

i've not been programing since many time ago and i can say I'm pretty a beginner.

In the last time I've been trying to do more complicated thinks but very often I find the same problem:

I do not know how to get an integer form an arraylist that i've created just for that, for saving integers and then use them.

Example: I've written an example for you to identify the problem, I know that I could get this drawing in another way, what I need is to get an int from the arrayList).

Thank you everybody, I would be very very pleased I've someone can explain it to me. Thank you very much to everybody!!
