Question
What is a List? What is the difference between an ArrayList and a LinkedList?
Answers
List is a collection of non-duplicate objects which are in an order. One can access the elements of a list in a specific order.

An ArrayList Class implements java.util.List interface and for storage it uses arrays, while a LinkedList class also implements java.util.List interface but uses linked list for storage.
Storage in arrays is faster than List.
The insertion and deletion of elements can’t be done in the middle of an ArrayList. To achieve this, a new array needs to be constructed. But in case of LinkedList, elements can be added and deleted from anywhere in the list.   Your Comment
