linkedHashMap

LinkedHashMap是一个继承自HashMap的类，它实现了Map接口。它的继承关系可以表示为：public class LinkedHashMap<K,V> extends HashMap<K,V> implements Map<K,V>。\[1\]与HashMap不同的是，LinkedHashMap还维护了一个Entry的双向链表，这个链表保证了插入的Entry中的顺序，也就是说，插入的顺序会被保留下来。这也是Linked的含义。\[2\]LinkedHashMap的结构图如下：\[2\]。

LinkedHashMap的概述可以表示为：public class LinkedHashMap<K,V> extends HashMap<K,V> implements Map<K,V>。\[3\]
