ZonedDateTime of() Method in Java with Examples

29 Jul, 2019
In ZonedDateTime class, there are three types of() method depending upon the parameters passed to it.
of() method of a ZonedDateTime class used to get an instance of ZonedDateTime from a year, month, day, hour, minute, second, nanosecond and time-zone.all these values year, month, day, hour, minute, second, nanosecond and time-zone are passed as parameter.
Syntax:
public static ZonedDateTime of(int year, int month, 
                               int dayOfMonth,
                               int hour, int minute,
                               int second, int nanoOfSecond,
                               ZoneId zone)

Parameters: This method accepts eight different parameters:
year – the year to represent, from MIN_YEAR to MAX_YEAR.
month – the month-of-year to represent, from 1 (January) to 12 (December).
dayOfMonth – the day-of-month to represent, from 1 to 31.
hour – the hour-of-day to represent, from 0 to 23.
minute – the minute-of-hour to represent, from 0 to 59.
second – the second-of-minute to represent, from 0 to 59.
nanoOfSecond – the nano-of-second to represent, from 0 to 999, 999, 999.
zone – the time-zone, not null.
Return value: This method returns the offset date-time.
Exception: This method throws DateTimeException if the value of any field is out of range, or if the day-of-month is invalid for the month-year.
Below programs illustrate the of() method:Program 1:
// Java program to demonstrate// ZonedDateTime.of() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create an ZonedDateTime object        // using of method        ZonedDateTime lt            = ZonedDateTime.of(                2020, 12, 3, 12, 20, 59,                90000, ZoneId.systemDefault());          // print result        System.out.println("ZonedDateTime : "                           + lt);    }}
ZonedDateTime : 2020-12-03T12:20:59.000090Z[Etc/UTC]

of(Clock clock) method of a ZonedDateTime class used to return an instance of ZonedDateTime from a local date, time and zone.all these localdate, localtime and zone are passed as parameter.
Syntax:
public static ZonedDateTime of(LocalDate date,
                               LocalTime time,
                               ZoneId zone)

Parameters: This method accepts three different parameter:
date – the local date
time – the local time
zone – the time-zone
Return value: This method returns the offset date-time.
Below programs illustrate the of() method:Program 1:
// Java program to demonstrate// ZonedDateTime.of() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a LocalDateTime        LocalDate localdate            = LocalDate.parse("2020-12-30");          // create a LocalTime        LocalTime localtime            = LocalTime.parse("17:52:49");          // create a zoneid        ZoneId zid            = ZoneId.of("Europe/Paris");          // create an ZonedDateTime object        // using of() method        ZonedDateTime zt            = ZonedDateTime.of(localdate,                               localtime, zid);          // print result        System.out.println("ZonedDateTime : "                           + zt);    }}
ZonedDateTime : 2020-12-30T17:52:49+01:00[Europe/Paris]

of() method of a ZonedDateTime class used to return an instance of ZonedDateTime from a localdatetime and zone.all these localdatetime and zone are passed as parameter.
Syntax:
public static ZonedDateTime of(LocalDateTime localDateTime,
                               ZoneId zone)

Parameters: This method accepts two different parameter:
localDateTime – the local date-time
time – the local time
Return value: This method returns the offset date-time.
Below programs illustrate the of() method:Program 1:
// Java program to demonstrate// ZonedDateTime.of() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a LocalDateTime        LocalDateTime local            = LocalDateTime                  .parse("2018-11-03T12:45:30");          // create a zoneid        ZoneId zid = ZoneId.of("Europe/Paris");          // create an ZonedDateTime object        // using of()        ZonedDateTime zt            = ZonedDateTime.of(                local, zid);          // print result        System.out.println("ZonedDateTime : "                           + zt);    }}
