The withZoneSameLocal() method of a ZonedDateTime class used to return a copy of this ZonedDateTime object by changing time-zone, without changing the local date-time if possible.The local date-time is only changed if it is invalid for the new zone, determined using the same approach as ofLocal(LocalDateTime, ZoneId, ZoneOffset).
Syntax:
public ZonedDateTime withZoneSameLocal(ZoneId zone)
Parameters: This method accepts one single parameter zone the time-zone to change to.It should not be null.
Return value: This method returns a ZonedDateTime based on this date-time with the requested zone.
Below programs illustrate the withZoneSameLocal() method:
Program 1:
// Java program to demonstrate// ZonedDateTime.withZoneSameLocal() method import java.time.*; public class GFG { public static void main(String[] args) { // create a ZonedDateTime object ZonedDateTime zonedDT = ZonedDateTime .parse( "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]"); // print ZonedDateTime System.out.println("ZonedDateTime of Calcutta: " + zonedDT); // apply withZoneSameLocal() ZonedDateTime zonedDT2 = zonedDT.withZoneSameLocal( ZoneId.of("Pacific/Fiji")); // print ZonedDateTime after withZoneSameLocal() System.out.println("ZonedDateTime of Fuji: " + zonedDT2); }} |
Output:
ZonedDateTime of Calcutta: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta] ZonedDateTime of Fuji: 2018-12-06T19:21:12.123+13:00[Pacific/Fiji]
Program 2:
// Java program to demonstrate// ZonedDateTime.withZoneSameLocal() method import java.time.*; public class GFG { public static void main(String[] args) { // create a ZonedDateTime object ZonedDateTime zonedDT = ZonedDateTime .parse( "2018-10-25T23:12:31.123+02:00[Europe/Paris]"); // print ZonedDateTime System.out.println("ZonedDateTime of Calcutta: " + zonedDT); // apply withZoneSameLocal() ZonedDateTime zonedDT2 = zonedDT .withZoneSameLocal( ZoneId.of("Canada/Yukon")); // print ZonedDateTime after withZoneSameLocal() System.out.println("ZonedDateTime of yukon: " + zonedDT2); }} |
Output:
ZonedDateTime of Calcutta: 2018-10-25T23:12:31.123+02:00[Europe/Paris] ZonedDateTime of yukon: 2018-10-25T23:12:31.123-07:00[Canada/Yukon]
