Java: Difference between ArrayList and LinkedList

Basically, they are just two different implementations of List interface.

LinkedList is implemented with a double-linked list; ArrayList is implemented with a dynamically resizing array.

所以基本的区别于list和array的区别很像，就是for random access, ArrayList is better; for adding and deleting, LinkedList is better.

LinkedList takes more space since it has to store both previous and next pointer. So large lists prefer arrayList.
