// getDayOfWeek() method

import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;
import java.time.zone.*;

public class GFG {
    public static void main(String[] argv)
    {

        // creating and initializing
        // ZoneOffsetTransitionRule Object
        ZoneOffsetTransitionRule zonetrans1
            = ZoneOffsetTransitionRule
                  .of(
                      Month.JANUARY, 12,
                      DayOfWeek.SUNDAY,
                      LocalTime.of(03, 24, 45),
                      false,
                      ZoneOffsetTransitionRule
                          .TimeDefinition
                          .STANDARD,
                      ZoneOffset.ofTotalSeconds(8),
                      ZoneOffset.ofTotalSeconds(10),
                      ZoneOffset.ofTotalSeconds(12));

        // getting Day Of Week
        // by using getDayOfWeek() method
        DayOfWeek day
            = zonetrans1.getDayOfWeek();

        // display the result
        System.out.println("Day Of Week : " + day);
    }
}

输出:

Day Of Week : SUNDAY

例 2:

import java.time.chrono.*;
import java.time.zone.*;

public class GFG {
    public static void main(String[] argv)
    {

        // creating and initializing
        // ZoneOffsetTransitionRule Object
        ZoneOffsetTransitionRule zonetrans1
            = ZoneOffsetTransitionRule
                  .of(
                      Month.JANUARY, 12,
                      DayOfWeek.MONDAY,
                      LocalTime.of(03, 24, 45),
                      false,
                      ZoneOffsetTransitionRule
                          .TimeDefinition
                          .STANDARD,
                      ZoneOffset.ofTotalSeconds(8),
                      ZoneOffset.ofTotalSeconds(10),
                      ZoneOffset.ofTotalSeconds(12));

        // getting Day Of Week
        // by using getDayOfWeek() method
        DayOfWeek day = zonetrans1.getDayOfWeek();

        // display the result
        System.out.println("Day Of Week : " + day);
