2.ArrayList vs. LinkedList vs.Vector 从层级图看出,他们都实现了List接口。他们使用方式相似。他们的主要区别在于实现方式,这会导致每个操作表现的性能不同。 ArrayList 被实现成为一个可变长数组,它的尺寸随着元素添加而动态增长。它的元素可被直接访问,使用get和set方法。ArrayList 本质上就是一个数组。

LinkeHashMap:LinkedHashMap是HashMap的一个子类,它保留插入的顺序。LinkedHashMap采用的hash算法和HashMap相同,但是它重新定义了数组中保存的元素Entry,该Entry除了保存当前对象的引用外,还保存了其上一个插入元素before和下一个插入元素after的引用,从而在哈希表的基础上又构成了双向链接列表。
