The ofInstant() method of a LocalTime class is used to obtain an instance of LocalTime from an Instant and zone ID passed as parameters.In this method First, the offset from UTC/Greenwich is obtained using the zone ID and instant. Then, the local time has calculated from the instant and offset.
Syntax:
public static LocalTime ofInstant(Instant instant, ZoneId zone)
Parameters: This method accepts two parameters:
- instant: It is the instant from which the LocalTime object is to be created. It should not be null.
- zone: It is the zone of the specified time. It should not be null.
Return value: This method returns the created LocalTime object created from the passed instant.
Below programs illustrate the ofInstant() method:
Program 1:
// Java program to demonstrate // LocalTime.ofInstant() method import java.time.*; public class GFG { public static void main(String[] args) { // create an Instant object Instant instant = Instant.parse( "2018-12-17T19:59:44.770Z" ); // print Instant System.out.println( "Instant: " + instant); // create ZoneId ZoneId zoneid = ZoneId.systemDefault(); // print ZoneId System.out.println( "ZoneId: " + zoneid); // apply ofInstant() LocalTime value = LocalTime.ofInstant(instant, zoneid); // print result System.out.println( "Generated LocalTime: " + value); } } |
Output:
Instant: 2018-12-17T19:59:44.770Z ZoneId: Etc/UTC Generated LocalTime: 19:59:44.770
Program 2:
// Java program to demonstrate // LocalTime.ofInstant() method import java.time.*; public class GFG { public static void main(String[] args) { // create an Instant object Instant instant = Instant.parse( "2016-11-11T09:19:22Z" ); // print Instant System.out.println( "Instant: " + instant); // apply ofInstant() LocalTime value = LocalTime.ofInstant(instant, ZoneId.of( "Asia/Dhaka" )); // print result System.out.println( "Generated LocalTime: " + value); } } |
Output:
Instant: 2016-11-11T09:19:22Z Generated LocalTime: 15:19:22
