DayOfWeek get() method in Java with Examples
  • Last Updated : 05 Nov, 2019

The get() method of java.time.DayOfWeek is an in-built function in Java which takes a TemporalField as parameter and gets the value of the specified field from this day-of-week as an int. The TemporalField is a field of date-time, such as month-of-year or hour-of-minute. Date and time is expressed using such fields. If the field is DAY_OF_WEEK then the value of the day-of-week, from 1 to 7, will be returned. All other ChronoField instances will throw an UnsupportedTemporalTypeException. The int value follows the ISO-8601 standard, from 1 (Monday) to 7 (Sunday).

Method Declaration:

public int get(TemporalField field);

Syntax:

int val = DayOfWeekObject.get(TemporalField field);

Parameters: This method takes field as parameter where:

  • field – is a Temporal field like the Chronafield.DAY_OF_WEEK.
  • DayOfWeekObject – represents the DayOfWeek object.

    Parameters: This method does not accepts any parameters.



    Return Value: The function returns int value of the day of the week, e.g, 1 for Monday, 2 for Tuesday and so on.

    Below programs illustrate the above method:
    Program 1:




    // Java Program Demonstrate get()
    // method of DayOfWeek
      
    import java.time.*;
    import java.time.DayOfWeek;
    import java.time.temporal.ChronoField;
      
    class DayOfWeekExample {
        public static void main(String[] args)
        {
            // Set a local date whose day is found
            LocalDate localDate
                = LocalDate.of(1947,
                               Month.AUGUST, 15);
      
            // Find the day from the local date
            DayOfWeek dayOfWeek
                = DayOfWeek.from(localDate);
      
            // Printing the day of the week
            // and its Int value
            System.out.println("Day of the Week on "
                               + localDate + " - "
                               + dayOfWeek.name());
      
            int val
                = dayOfWeek.get(ChronoField.DAY_OF_WEEK);
      
            System.out.println("Int Value of "
                               + dayOfWeek.name()
                               + " - " + val);
        }
    }
    Output:
    Day of the Week on 1947-08-15 - FRIDAY
    Int Value of FRIDAY - 5
    

    Program 2:




    // Java Program Demonstrate get()
    // method of DayOfWeek
    import java.time.*;
    import java.time.DayOfWeek;
    import java.time.temporal.ChronoField;
      
    class DayOfWeekExample {
        public static void main(String[] args)
        {
            // Set a local date whose day is found
            LocalDate localDate
                = LocalDate.of(2015,
                               Month.JULY, 13);
      
            // Find the day from the local date
            DayOfWeek dayOfWeek
                = DayOfWeek.from(localDate);
      
            // Printing the day of the week
            // and its Int value
            System.out.println("Day of the Week on "
                               + localDate + " - "
                               + dayOfWeek.name());
      
            int val
                = dayOfWeek.get(ChronoField.DAY_OF_WEEK);
      
            System.out.println("Int Value of "
                               + dayOfWeek.name()
                               + " - " + val);
        }
    }
    Output:
    Day of the Week on 2015-07-13 - MONDAY
    Int Value of MONDAY - 1
