Tags: Java LocalDateTime Java Instant Java 8

In this Java core tutorial we learn how to convert a java.time.LocalDateTime object into java.time.Instant object in Java programming language.

How to convert LocalDateTime to Instant in Java

In Java, to convert a LocalDateTime object to Instant object we can firstly convert it to ZonedDateTime object and call the toInstant() method to get Instant value as following Java code.

ConvertLocalDateTimeToInstantExample1.java 

import java.time.Instant;
import java.time.LocalDateTime;
import java.time.ZoneId;

public class ConvertLocalDateTimeToInstantExample1 {
    public static void main(String... args) {
        LocalDateTime localDateTime = LocalDateTime.now();
        Instant instant = localDateTime.atZone(ZoneId.systemDefault()).toInstant();

        System.out.println("LocalDateTime: " + localDateTime);
        System.out.println("Instant: " + instant);
    }
}
The output as below. 
LocalDateTime: 2022-04-24T13:21:40.209901200
Instant: 2022-04-24T06:21:40.209901200Z
