有没有ArraySet和ArrayMap这样的东西？ [英] Is there such thing as an ArraySet and ArrayMap?

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 LinkedHashMap 将保留插入顺序，并且 TreeMap 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.
