本文探讨了ArrayList与LinkedList这两种List接口实现方式的区别。ArrayList基于动态调整大小的数组实现，适合随机访问；而LinkedList采用双向链表结构，对于元素的插入和删除操作更为高效，但会占用更多内存。

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.

当 arr 是一个array时，写Java开始的corner case常常会写类似下面的语句： if(arr == null || arr.length == 0){ return 0; } 其实这是两个条件， arr==null 和 arr.length==0 是不同的： arr.length == 0说明 arr is an empty array, which means an
