Description
### [Map类及其主要的实现类](https://blog.csdn.net/songbai1997/article/details/83042876)
Map接口提供将键映射至值的功能，每个键最多只能映射至一个值
**Map接口的主要实现类主要有HashMap、LinkedHashMap和TreeMap**
- HashMap以**哈希表**为内核实现Map接口，它的键-值对的顺序和放入的**顺序无关**；**键无重复**
- LinkedHashMap以**哈希表和链表**为内核实现Map接口，**键-值对的顺序是放入的顺序**；**键无重复**
- TreeMap以**二叉树**为内核实现Map接口，**键-值对按照键的升序进行排列**；**键值无重复**
