Answer
ArrayList is backed by an array, allowing fast indexed access.
ArrayList stores elements in a dynamic array, providing O(1) time complexity for accessing elements by index. This makes it suitable for scenarios where frequent read operations by index are needed, like accessing a product at a specific position in a list.
