 ArrayList是一种线性数据结构，底层基于数组实现。ArrayList会根据实际需要动态调整容量，每次扩容增加50%。
 
 ArrayList和[Vector](js-apis-vector.md)相似，都是基于数组实现。它们都可以动态调整容量，但Vector每次扩容增加1倍。

 # @ohos.util.HashSet (非线性容器HashSet)
 
-> **说明：**
-> 本模块首批接口从API version 8开始支持。后续版本的新增接口，采用上角标单独标记接口的起始版本。
-
 HashSet基于[HashMap](js-apis-hashmap.md)实现。在HashSet中，只对value对象进行处理。
 
 HashSet和[TreeSet](js-apis-treeset.md)相比，HashSet中的数据无序存放，即存放元素的顺序和取出的顺序不一致，而TreeSet是有序存放。它们集合中的元素都不允许重复，但HashSet允许放入null值，TreeSet不允许。
 
 **推荐使用场景：** 可以利用HashSet不重复的特性，当需要不重复的集合或需要去重某个集合的时候使用。
