JDK核心JAVA源码解析（7）- 集合相关（1） - LinkedList

想写这个系列很久了，对自己也是个总结与提高。原来在学JAVA时，那些JAVA入门书籍会告诉你一些规律还有法则，但是用的时候我们一般很难想起来，因为我们用的少并且不知道为什么。知其所以然方能印象深刻并学以致用。本篇文章针对JAVA中集合类LinkedList进行分析，通过代码解释Java中的Fail-...

Java集合源码剖析——基于JDK1.8中LinkedList的实现原理（下）

3.7 unlinkFirst方法删除操作与添加操作大同小异，需要把当前节点的前驱节点的后继修改为当前节点的后继，以及当前节点的后继结点的前驱修改为当前节点的前驱。unlinkFirst方法是在表头进行元素的删除，首先做的是将要删除元素的item值保存到一个临时变量element中，最终返回。同时将...

java集合系列（5）LinkedList

一、LinkedList认识1、由链表认识LinkedList我们应该都学过数据结构与算法，如果你知道链表的实现原理，那么你就可以直接看LinkedList的基本认识了，可以跳过本小节，如果你没学过，或者是不牢固，那么就先看看本小节再往下面学习吧。我们想要认识链表有一个例子可以形象的去表示，我们都看...

Java集合：LinkedList详解

概述本文就LinkedList的几个主要方法展开介绍，并结合几个图片来介绍几个重要操作。基础属性transient int size = 0; // 节点数量 /** * Pointer to first node. * Invariant: (first == null &&a...

java集合之LinkedList继承的图

我们上一次说到List的ArrayList，我们这次去看下LinkedList—顾名思义是链表，链表的优点就不用说了吧，增删效率比较高（具体的朋友们上网看吧），先来看下LinkedList的整体构架：

Java集合干货——LinkedList源码分析

前言在上篇文章中我们对ArrayList对了详细的分析，今天我们来说一说LinkedList。他们之间有什么区别呢？最大的区别就是底层数据结构的实现不一样，ArrayList是数组实现的（具体看上一篇文章），LinedList是链表实现的。至于其他的一些区别，可以说大部分都是由于本质不同衍生出来的...
