本文整理了Java中java.util.Collection.addAll()方法的一些代码示例，展示了Collection.addAll()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。Collection.addAll()方法的具体详情如下：
包路径：java.util.Collection
类名称：Collection
方法名：addAll

Collection.addAll介绍

[英]Attempts to add all of the objects contained in Collectionto the contents of this Collection (optional). If the passed Collectionis changed during the process of adding elements to this Collection, the behavior is not defined.
[中]尝试将Collection中包含的所有对象添加到此集合的内容（可选）。如果在向该集合添加元素的过程中更改了传递的集合，则不会定义该行为。
