本文整理了Java中org.apache.commons.collections4.CollectionUtils.containsAll()方法的一些代码示例，展示了CollectionUtils.containsAll()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。CollectionUtils.containsAll()方法的具体详情如下：
包路径：org.apache.commons.collections4.CollectionUtils
类名称：CollectionUtils
方法名：containsAll

CollectionUtils.containsAll介绍

[英]Returns true iff all elements of coll2 are also contained in coll1. The cardinality of values in coll2 is not taken into account, which is the same behavior as Collection#containsAll(Collection).

In other words, this method returns true iff the #intersection of coll1 and coll2 has the same cardinality as the set of unique values from coll2. In case coll2 is empty, truewill be returned.

This method is intended as a replacement for Collection#containsAll(Collection)with a guaranteed runtime complexity of O(n + m). Depending on the type of Collection provided, this method will be much faster than calling Collection#containsAll(Collection) instead, though this will come at the cost of an additional space complexity O(n).
[中]如果coll1中还包含coll2的所有元素，则返回true。coll2中的值的基数不被考虑，这与Collection#containsAll（Collection）的行为相同。
换句话说，如果coll1和coll2的#交集与coll2的唯一值集具有相同的基数，则此方法返回true。如果coll2为空，将返回truel。
此方法旨在替代保证运行时复杂性为O（n+m）的Collection#containsAll（Collection）。根据提供的集合类型，此方法将比调用Collection#containsAll（Collection）快得多，尽管这将以额外的空间复杂性O（n）为代价。
