CollectionUtils.intersection介绍

[英]Returns a Collection containing the intersection of the given Collections.

The cardinality of each element in the returned Collectionwill be equal to the minimum of the cardinality of that element in the two given Collections.
[中]返回包含给定集合交集的集合。
返回集合中每个元素的基数将等于两个给定集合中该元素的最小基数。
