问题描述
如果有这样的话,我想要一张保留元素顺序的地图。
I would like a map that preserves the order of the elements if there is such a thing.
我知道它会不在HashMap附近执行,但我只计划将它用于小型/临时程序。
I am aware that it would not perform near as well as a HashMap, but I only plan to use it for small/temporary programs.
推荐答案
没有ArrayMap 。 :)
There's no ArrayMap. :)
但将保留插入顺序,并且将根据键的自然顺序进行排序。
But a LinkedHashMap will preserve the insertion order, and a TreeMap will order based on the keys' natural ordering.
