ZonedDateTime ofStrict() Method in Java with Examples Last Updated : 13 Sep, 2021 Comments Improve Suggest changes Like Article Like Report ofStrict() method of ZonedDateTime class used to create an instance of ZonedDateTime strictly validating the combination of local date-time, offset and zone ID where all three Local date-time, ZoneOffset and ZoneId are passed as parameter.If the offset is invalid, an exception is thrown. Syntax: public static ZonedDateTime ofStrict(LocalDateTime localDateTime, ZoneOffset offset, ZoneId zone) Parameters: This method accepts three parameters localDateTime which is the local date-time, offset which is the zone offset and zone which is the time-zone.Return value: This method returns the zoned date-time.Below programs illustrate the ofStrict() method: Program 1: Java // Java program to demonstrate // ZonedDateTime.ofStrict() method import java.time.*; public class GFG { public static void main(String[] args) { // create local date time object LocalDateTime ldt = LocalDateTime .parse("2019-01-29T23:55:59.00"); // create ZoneOffset ZoneOffset zoneOffset = ZoneOffset.ofHours(1); // create a ZonID ZoneId zone = ZoneId.of("Europe/Paris"); // apply ofStrict method // of ZonedDateTime class ZonedDateTime zt = ZonedDateTime .ofStrict( ldt, zoneOffset, zone); // print the result System.out.println("ZonedDateTime is " + zt); } } Output: ZonedDateTime is 2019-01-29T23:55:59+01:00[Europe/Paris] Program 2: Java // Java program to demonstrate // ZonedDateTime.ofStrict() method import java.time.*; public class GFG { public static void main(String[] args) { // create local date-time object LocalDateTime ldt = LocalDateTime .parse("2019-01-29T23:55:59.00"); // create ZoneOffset ZoneOffset zoneOffset = ZoneOffset.ofHours(0); // create a ZonID ZoneId zone = ZoneId.of("UTC"); // apply ofStrict method // of ZonedDateTime class ZonedDateTime zt = ZonedDateTime .ofStrict( ldt, zoneOffset, zone); // print the result System.out.println("ZonedDateTime is " + zt); } } Output: ZonedDateTime is 2019-01-29T23:55:59Z[UTC] References: https://docs.oracle.com/javase/10/docs/api/java/time/ZonedDateTime.html#ofStrict(java.time.LocalDateTime, java.time.ZoneOffset, java.time.ZoneId) Comment More infoAdvertise with us Next Article ZonedDateTime ofStrict() Method in Java with Examples A AmanSingh2210 Follow Improve Article Tags : Java Java-Functions Java-time package Java-ZonedDateTime Practice Tags : Java Similar Reads ZonedDateTime of() Method in Java with Examples In ZonedDateTime class, there are three types of() method depending upon the parameters passed to it. of(int year, int month, int dayOfMonth, int hour, int minute, int second, int nanoOfSecond, ZoneId zone) of() method of a ZonedDateTime class used to get an instance of ZonedDateTime from a year, mo 3 min read ZonedDateTime toString() method in Java with Examples The toString() method of a ZonedDateTime class is used to return this ZonedDateTime as a String. The string consists of the LocalDateTime followed by the ZoneOffset. If the ZoneId is not the same as the offset, then the ID is output.
