The withZoneSameLocal() method of a ChronoZonedDateTime interface used to return a copy of this ChronoZonedDateTime object by changing the time-zone and without the instant.This method is based on retaining the same instant, thus gaps and overlaps in the local time-line have no effect on the result.
Syntax:
ChronoZonedDateTime 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 ChronoZonedDateTime based on this date-time with the requested zone.
Below programs illustrate the withZoneSameLocal() method:
Program 1:
// Java program to demonstrate// ChronoZonedDateTime.withZoneSameLocal() method import java.time.*;import java.time.chrono.*; public class GFG { public static void main(String[] args) { // create a ChronoZonedDateTime object ChronoZonedDateTime zonedDT = ZonedDateTime .parse( "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]"); // print ChronoZonedDateTime System.out.println("ChronoZonedDateTime of Calcutta: " + zonedDT); // apply withZoneSameLocal() ChronoZonedDateTime zonedDT2 = zonedDT .withZoneSameLocal( ZoneId.of("Pacific/Fiji")); // print ChronoZonedDateTime after withZoneSameLocal() System.out.println("ChronoZonedDateTime of Fuji: " + zonedDT2); }} |
Output:
ChronoZonedDateTime of Calcutta: 2018-12-06T19:21:12.123+05:30[Asia/Calcutta] ChronoZonedDateTime of Fuji: 2018-12-06T19:21:12.123+13:00[Pacific/Fiji]
Program 2:
// Java program to demonstrate// ChronoZonedDateTime.withZoneSameLocal() method import java.time.*;import java.time.chrono.*; public class GFG { public static void main(String[] args) { // create a ChronoZonedDateTime object ChronoZonedDateTime zonedDT = ZonedDateTime .parse( "2018-10-25T23:12:31.123+02:00[Europe/Paris]"); // print ChronoZonedDateTime System.out.println("ChronoZonedDateTime of Calcutta: " + zonedDT); // apply withZoneSameLocal() ChronoZonedDateTime zonedDT2 = zonedDT .withZoneSameLocal( ZoneId.of("Canada/Yukon")); // print ChronoZonedDateTime after withZoneSameLocal() System.out.println("ChronoZonedDateTime of yukon: " + zonedDT2); }} |
Output:
ChronoZonedDateTime of Calcutta: 2018-10-25T23:12:31.123+02:00[Europe/Paris] ChronoZonedDateTime of yukon: 2018-10-25T23:12:31.123-07:00[Canada/Yukon]
