This article will explain in detail how to use source code to analyze LinkedList, the content of the article is of high quality, so the editor will share it for you as a reference. I hope you will have a certain understanding of the relevant knowledge after reading this article.

Introduction to LinkedList public class LinkedList extends AbstractSequentialList implements List, Deque, Cloneable, java.io.Serializable {}

LinkedList inherits AbstractSequentialList, and the main method is implemented through iterators.

LinkedList implements List; so it is a queue that supports operations such as add, delete, modify, traverse, and so on.

LinkedList implements that Deque; can be used as a double-ended queue.

LinkedList implements the Cloneable interface and overrides the clone method, so it can be cloned.

LinkedList implements the Serializable interface, so it can be serialized.

The operation of LinkedList is not thread safe

Member variable / * head node of current collection * * / tail node of transient Node first;/** current collection * * / actual number of nodes of transient Node last;/** current collection * * / transient int size;Node analysis private static class Node {E item; Node next; Node prev; Node (Node prev, E element, Node next) {this.item = element; this.next = next This.prev = prev;}}

The specific node class of the two-way linked list, and each node contains three variables:

Item saves the specific data of the current node

Prev saves the previous node of the current node

Next saves the next node of the current node

Constructor / * * construct an empty set * * / public LinkedList () {} / * * construct a LinkedList * * / public LinkedList (Collection) based on the existing set
