Given an ArrayList a , write an expression that refers to the first element of the ArrayList. So, if the array a held the following values: 33,14,97,265, 84, then the value of your expression should be 33. I tried: Object obj = arrayList.get(33); What am I doing wrong?

the ArrayList is "a" and the first element is indexed to "0" so to refer to the fist element it would be: a.get(0); If you go to page 73 in the Greenfoot book and read there you be able to understand it better.

Thanks so much, I think I get it, a.get(o) refers the the first number in this situation which would be 33!! I'm so excited!!!
