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, LinkedL...

Java LinkedList and ArrayList are different in many aspects, and we need to understand both to decide when to use which class.
arraylist stores its elements in memory consecutively, but linkedlist don’t have to because of the pointers. different interface it implemented. arraylist implement list interface and linkedlist implement list interface and deque interface. different using scenarios: arraylist works better when we have l...
In this guide, you will learn difference between ArrayList and LinkedList in Java. ArrayList and LinkedList both implements List interface and their methods and results are almost identical. However there are few differences between them which make one b
ArrayList in Java maintains a contiguous block of memory, which can lead to better cache performance. However, it might require more memory due to capacity resizing. LinkedList, with its node-based structure, uses more memory per element due to the additional previous and next references. ...
