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

Set.equals介绍

[英]Compares the specified object to this set, and returns true if they represent the same object using a class specific comparison. Equality for a set means that both sets have the same size and the same elements.
[中]将指定对象与此集合进行比较，如果它们使用特定于类的比较表示相同对象，则返回true。一个集合的相等意味着两个集合具有相同的大小和相同的元素。
