IsoChronology zonedDateTime(Instant, ZoneId) method in Java with Example

The zonedDateTime() method of java.time.chrono.IsoChronology class is used to retrieve the date and time of a particular zone according to Iso calendrer from a particular instant.

Syntax:

public ZonedDateTime zonedDateTime(Instant instant,
                                   ZoneId zone)

Parameter: This method takes the following arguments as parameter.

  • instant: which is the object of type instant
  • zone: which is the object of type zoneId

Return Value: This method returns the date and time of a particular zone according to Iso calendrer from a particular instant.

Below are the examples to illustrate the zonedDateTime() method:

                               + "not form a date");
            System.out.println("Exception thrown: " + e);
        }
