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 ...
ArrayList providesget(int index) method which directly find the element at given index location. ItisoforderO(1). LinkedList also provideget(int index) method BUT it first traverses all nodestoreach the correct node. It makes the performance variable.InbestcaseitisO(1)andinworstcaseitisO(n)....

I conclude by saying that use of ArrayList is better than using Vector as it performs faster and better. Related Differences: Difference Between Thread Class and Runnable Interface in Java Difference Between ArrayList and LinkedList in Java
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
Difference Between ArrayList in Java and LinkedList in Java Table of Contents Key Differences ArrayList in Java is a dynamic array, allowing for efficient random access and size changes. It stores elements in a contiguous memory location, enabling quick retrieval via index. However, resizing an Arra...
