本文主要是介绍【DataStructure】Descriptioin and usage of List，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
Statements: This blog was written by me, but most of content is quoted from book【Data Structure with Java Hubbard】
【Description】
Alistis a collection of elements that are accessible sequentially: the first element, followed by the second element, followed by the third element, and so on. This is called sequential accessor linked access(as opposed to direct or indexed access)
【Interface】
From the JCF inheritance hierarchy , you can see that the Queue, Deque, and Setinterfaces all extend the Listinterface. Consequently, all of the List,Queue, Deque, and Setclasses implement the Listinterface. This includes the concrete classes: ArrayList, Vector, LinkedList, PriorityQueue, ArrayDeque,EnumSet,HashSet,LinkedHashSet,and TreeSet.the JCF provides both linked and indexed implementations of the Listinterface: the LinkedList class uses sequential access, while the ArrayListclass provides direct access.
