HashMap是基于哈希表实现,以键值对的形式存储,采用了数组和链表的数据结构,能在查询和修改方便继承了数组的线性查找和链表的寻址修改。
Fifth abundantly made Give sixth hath. Cattle creature i be don't them.
Far far away, behind the word mountains, far from the countries Vokalia and Consonantia, there live the blind texts. A small river named Duden flows by their place and supplies it with the necessary regelialia. It is a paradisematic country, in which roasted parts of sentences fly into your mouth.

ConcurrentSkipListMap提供了一种线程安全的并发访问的排序映射表。内部是SkipList(跳表)结构实现,在理论上能够在O(log(n))时间内完成查找、插入、删除操作。
跳表是一个随机化的数据结构,实质就是一种可以进行二分查找的有序链表。跳表在原有的有序链表上面增加了多级索引,通过索引来实现快速查找。跳表不仅能提高搜索性能,同时也可以提高插入和删除操作的性能。
