DayOfWeek get() method in Java with Examples

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
