LinkedHashMap与HashMap的区别

LinkedHashMap与HashMap的区别在于LinkedHashMap在继承了HashMap的大部分功能之外，还具有排序的功能。具体来说，LinkedHashMap使用双向链表来保证元素的顺序，而HashMap则没有这个功能。另外，LinkedHashMap新增了三个属性，分别是head（链表的头部）、tail（链表的尾部）和accessOrder（迭代顺序标识）。所以，LinkedHashMap可以按照插入顺序或者访问顺序来迭代元素，而HashMap只能按照哈希表的存储顺序来迭代元素。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
