What describes the LinkedList class best?

  1. Uses a hash table for storage

  2. Stores elements in a double linked list

  3. Cannot have its elements iterated

  4. Offers constant time performance for all operations

The correct answer is: Stores elements in a double linked list

The LinkedList class is designed to store elements in a double linked list, where each element is connected to the ones before and after it. This allows for efficient insertion and deletion of elements in the list. Option A is incorrect because LinkedList does not use a hash table for storage. Option C is incorrect because the elements in a LinkedList can be iterated, or accessed in sequence. Option D is incorrect because the performance of operations in a LinkedList is not constant, but rather depends on the length of the list. Therefore, the best description of the LinkedList class is that it stores elements in a double linked list.
