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

Vector.of介绍

[英]Returns a singleton Vector, i.e. a Vector of one element.
[中]返回单个向量，即一个元素的向量。
