下面的程序说明了 getDayOfWeek() 方法：

方案一：

// 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);
    }
}

输出：

day-of-week:THURSDAY

方案二：

// 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);
    }
}

输出：

day-of-week:WEDNESDAY
