第1部分 Vector介绍 Vector简介 Vector 是矢量队列,它是JDK1.0版本添加的类.继承于AbstractList,实现了List, RandomAccess, Cloneable这些接口.Vector 继承了AbstractList,实现了List:所以,它是一个队列,支持相关的添加.删除.修改.遍历等功能.Vector 实现了RandmoAccess接口,即提供了随机访问功能.RandmoAccess是java中用来被List实现,为List提供快速访问功能的.在Vecto…

注:博主java集合框架源码剖析系列的源码全部基于JDK1.8.0版本.本博客将从源码角度带领大家学习关于HashSet的知识. 一HashSet的定义: public class HashSet<E> extends AbstractSet<E> implements Set<E>, Cloneable, java.io.Serializable 可以看到HashSet继承自AbstractSet同时实现了Set,Cloneable,Serializable三个接口,…

前言:之所以打算写java集合框架源码剖析系列博客是因为自己反思了一下阿里内推一面的失败(估计没过,因为写此博客已距阿里巴巴一面一个星期),当时面试完之后感觉自己回答的挺好的,而且据面试官最后说的这几天可能会和你联系来看当时以为自己一面应该是通过的,但是事与愿违,痛定思痛,仔细回顾了一下面试官问我的整个过程,感兴趣的可以参看我的博客:[阿里内推一面]记我人生的处女面.感觉自己回答的不是很好的地方就是关于java方面的,所以下定决心将java中的核心知识来个大的梳理,java中的核心知识可能很多,…
