1、Doubly-linked list implementation of the List and Deque interfaces. Implements all optional list operations, and permits all elements (including null).这告诉我们，linkedList是一个双向链表，并且实现了List和Deque接口中所有的列表操作，并且能存储任何元素，包括null，这里我们可以知道linkedList除了可以当链表...

For many cases, theArrayListis more efficient as it is common to need access to random items in the list, but theLinkedListprovides several methods to do certain operations more efficiently: MethodDescriptionTry it addFirst()Adds an item to the beginning of the listTry it » ...
链表(Linked list)是一种常见的基础数据结构,是一种线性表,但是并不会按线性的顺序存储数据,而是在每一个节点里存到下一个节点的地址。 链表可分为单向链表和双向链表。 一个单向链表包含两个值: 当前节点的值和一个指向下一个节点的链接。 一个双向链表有三个整数值: 数值、向后的节点链接、向前的节点链接...
