本文整理了Java中io.vavr.collection.HashSet.of()方法的一些代码示例，展示了HashSet.of()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。HashSet.of()方法的具体详情如下：
包路径：io.vavr.collection.HashSet
类名称：HashSet
方法名：of

HashSet.of介绍

[英]Returns a singleton HashSet, i.e. a HashSet of one element.
[中]返回单个哈希集，即一个元素的哈希集。
