本文整理了Java中org.apache.commons.collections.CollectionUtils.disjunction()方法的一些代码示例，展示了CollectionUtils.disjunction()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.disjunction()方法的具体详情如下：
包路径：org.apache.commons.collections.CollectionUtils
类名称：CollectionUtils
方法名：disjunction

CollectionUtils.disjunction介绍

[英]Returns a Collection containing the exclusive disjunction (symmetric difference) of the given Collections.

The cardinality of each element e in the returned Collectionwill be equal to max(cardinality(e,a),cardinality(e,b)) - min(cardinality(e,a),cardinality(e,b)).

This is equivalent to #subtract( #union, #intersection) or #union( #subtract, #subtract).
[中]返回包含给定集合的独占析取（对称差）的集合。
返回集合中每个元素e的基数将等于max（基数（e，a），基数（e，b））-min（基数（e，a），基数（e，b））。
这相当于#减法（#并集，#交集）或#并集（#减法，#减法）。
