英文:
Equivalent of moment react in java
问题
我必须找到开始加载时间和完成加载时间事件之间的差异。开始加载时间在Java中，而结束时间在React中。
在React中，我有这样的代码：
completeLoad = moment();
我想要记录Java中的初始加载时间，然后找到两者之间的差异。我不确定如何在Java中以类似 moment() 的格式记录时间。在这方面需要一些帮助。
英文:
I have to find the difference between the start and the complete load time event. The start load is in java whereas end is in react.
In react I have this
completeLoad = moment();
I want to record the initial load time in java and then find the difference between the two. I am not sure how to record time in java in similar format as momemt(). Need some help here.

在Java中，您可以使用Instant来表示时间线上的单个瞬时点。Instant#now可以从系统时钟获取当前的瞬时点。
import java.time.Instant;public class Main {public static void main(String[] args) {Instant now = Instant.now();System.out.println(now);System.out.println(now.toEpochMilli());System.out.println(now.getEpochSecond());}}
示例运行的输出:
2020-10-07T17:16:10.487996Z16020909704871602090970
英文:
In Java, you have Instant which models a single instantaneous point on the time-line. Instant#now gives you the current instant from the system clock.
import java.time.Instant;public class Main {public static void main(String[] args) {Instant now = Instant.now();System.out.println(now);System.out.println(now.toEpochMilli());System.out.println(now.getEpochSecond());}}
Output from a sample run:
2020-10-07T17:16:10.487996Z16020909704871602090970
