Choice A is false: The [] notation is compact and easy to use. Choice B is not a valid reason because an array arr also provides instant access to its length with the quantity arr.length.

Choice E is false: W het her a String objec t is arr[i] or list.get(i), t he String methods are equally easy to invoke.
