Java: Difference between ArrayList and LinkedList

本文探讨了ArrayList与LinkedList这两种List接口实现方式的区别。ArrayList基于动态数组实现,适合随机访问;而LinkedList采用双向链表结构,更适合频繁插入和删除操作。由于LinkedList需要存储前后指针,因此在空间使用上不如ArrayList高效。

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.
