arraylist

Hello,

I've got a Problem with ArrayList. I need it to store a result. Because I want to start with element n I tryed to give the ArrayList a capacity with ensureCapacity(n+1) to use set(n,x) but I get an IndexOutOfBoundsException.

I tryed to store n add(x) before the use of set and this works.

So I'd like to know why it doesn't work on my way and how to solve this because put n times a add(x) isn't a good style ;-)

Best regards, Sebastian
