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

Duration.getNano介绍

[英]Gets the number of nanoseconds within the second in this duration.

The length of the duration is stored using two fields - seconds and nanoseconds. The nanoseconds part is a value from 0 to 999,999,999 that is an adjustment to the length in seconds. The total duration is defined by calling this method and #getSeconds().

A Duration represents a directed distance between two points on the time-line. A negative duration is expressed by the negative sign of the seconds part. A duration of -1 nanosecond is stored as -1 seconds plus 999,999,999 nanoseconds.
[中]获取此持续时间内秒内的纳秒数。
持续时间的长度使用两个字段存储-秒和纳秒。纳秒部分是一个从0到99999999的值，它是对以秒为单位的长度的调整。通过调用此方法和#getSeconds（）定义总持续时间。
持续时间表示时间线上两点之间的定向距离。负持续时间由秒部分的负号表示。-1纳秒的持续时间存储为-1秒加9999999纳秒。
