The getDayOfWeek() method of a ZonedDateTime class is used to get the day-of-week field from this ZonedDateTime, which is an enum DayOfWeek.Additional information can be obtained from the DayOfWeek. This includes textual names of the values.
Syntax:
public DayOfWeek getDayOfWeek()
Parameters: This method does not take any parameters.
Return value: This method returns an enum DayOfWeek representing day-of-week.
Below programs illustrate the getDayOfWeek() method:
Program 1:
// Java program to demonstrate// ZonedDateTime.getDayOfWeek() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a ZonedDateTime object        ZonedDateTime zoneddatetime            = ZonedDateTime.parse(                "2018-12-06T19:21:12.123+05:30[Asia/Calcutta]");          // get day-of-week field        DayOfWeek value = zoneddatetime.getDayOfWeek();          // print result        System.out.println("day-of-week:" + value);    }} |
Output:
day-of-week:THURSDAY
Program 2:
// Java program to demonstrate// ZonedDateTime.getDayOfWeek() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a ZonedDateTime object        ZonedDateTime zoneddatetime            = ZonedDateTime.parse(                "2018-10-24T23:12:31.123+02:00[Europe/Paris]");          // get day-of-week field        DayOfWeek value = zoneddatetime.getDayOfWeek();          // print result        System.out.println("day-of-week:" + value);    }} |
Output:
day-of-week:WEDNESDAY
