Java Instant.atZone() Method with Examples

Tags: Java Instant Java 8

In this Java core tutorial we learn how to use the java.time.Instant.atZone() method to convert an Instant object into an ZonedDateTime object in Java programming language.

How to use Instant.atZone() method

In Java program, with a given Instant object we can use Instant.atZone(ZoneId zone) method to convert it to an ZonedDateTime object in specified time zone as the Java code below.

InstantAtZoneExample1.java

import java.time.Instant;
import java.time.ZoneId;
import java.time.ZonedDateTime;

public class InstantAtZoneExample1 {
    public static void main(String... args) {
        Instant instant = Instant.parse("2022-07-11T08:00:30Z");

        ZoneId zoneId = ZoneId.of("Australia/Sydney");
        ZonedDateTime zonedDateTime = instant.atZone(zoneId);

        System.out.println("Instant: " + instant);
        System.out.println("ZonedDateTime: " + zonedDateTime);
    }
}
The output as below.
Instant: 2022-07-11T08:00:30Z
ZonedDateTime: 2022-07-11T18:00:30+10:00[Australia/Sydney]

Happy Coding 😊
