What are the three main disadvantages of an ArrayList?
What will be an ideal response?
1) They are less efficient than arrays; (2) they do not have the square bracket notation, and
so using an ArrayList is sometimes notationally more awkward than using ordinary arrays; and (3)
the base type of an ArrayList must be a class type (or other reference type); it cannot be a primitive
type, such as int, double, or char.
