The withFixedOffsetZone() method of a ZonedDateTime class is used to return a copy of this ZonedDateTime object with the zone ID set to the offset. This method returns a ZonedDateTime where the zone ID is the same as getOffset().The local date-time, offset and instant of the returned ZonedDateTime will be the same as in this date-time.
Syntax:
public ZonedDateTime withFixedOffsetZone()
Parameters: This method accepts no parameters.
Return value: This method returns a ZonedDateTime with the zone ID set to the offset.
Below programs illustrate the withFixedOffsetZone() method:
Program 1:
// Java program to demonstrate// ZonedDateTime.withFixedOffsetZone() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a ZonedDateTime object        ZonedDateTime zonedDT            = ZonedDateTime                  .ofLocal(                      LocalDateTime.of(2018, 11, 4, 1, 25, 43),                      ZoneId.of("US/Central"),                      ZoneOffset.ofHours(-6));          // print ZonedDateTime        System.out.println("Before withFixedOffsetZone(): "                           + zonedDT);          // apply withFixedOffsetZone()        ZonedDateTime zonedDT2            = zonedDT.withFixedOffsetZone();          // print ZonedDateTime after withFixedOffsetZone()        System.out.println("After withFixedOffsetZone(): "                           + zonedDT2);    }} |
Output:
Before withFixedOffsetZone(): 2018-11-04T01:25:43-06:00[US/Central] After withFixedOffsetZone(): 2018-11-04T01:25:43-06:00
Program 2:
// Java program to demonstrate// ZonedDateTime.withFixedOffsetZone() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a ZonedDateTime object        ZonedDateTime zonedDT            = ZonedDateTime.now();          // print ZonedDateTime        System.out.println("Before withFixedOffsetZone(): "                           + zonedDT);          // apply withFixedOffsetZone()        ZonedDateTime zonedDT2            = zonedDT.withFixedOffsetZone();          // print ZonedDateTime after withFixedOffsetZone()        System.out.println("After withFixedOffsetZone(): "                           + zonedDT2);    }} |
Output:
Before withFixedOffsetZone(): 2018-12-17T05:16:41.417Z[Etc/UTC] After withFixedOffsetZone(): 2018-12-17T05:16:41.417Z
