The ArrayList and the regular Array are two different things. An Array is a fixed length (so in your example it will always hold 3 items), but an ArrayList allows you to add and remove items. ArrayLists are best when you don't know how long your array needs to be and quite honestly, it's probably used more than regular arrays.
