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

Objects.requireNonNull介绍

[英]Returns o if non-null, or throws NullPointerException.
[中]如果为非null，则返回o，或引发NullPointerException。
