[SOLVED] Equivalent of moment react in java

Equivalent of moment react in java

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.

Solution

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:
