I've played around with arrays and arrayLists. Sorting is a breeze with arrayLists but I can not say the same with arrays. You have to make a for loop and filter the results and it's a pain. As far as I can see arrayList are just a better version of arrays. So why use arrays? Is there something they can do better.

Sorting with arrays and ArrayLists is equally easy: there are already implementations for sorting both of them:
The reasons for using one of the other are more of memory concerns, speed concerns or because your problems is better suited to be solved with one or the other.
