ZonedDateTime getDayOfYear() method in Java with Examples

The getDayOfYear() method of a ZonedDateTime class is used to get the day-of-year field from this ZonedDateTime. This method returns the integer value for the day-of-year from 1 to 365, or 366 in a leap year.

Syntax:

public int getDayOfYear()

Parameters: This method does not take any parameters.

Return value: This method returns an integer representing day-of-year, from 1 to 365, or 366 in a leap year.

Below programs illustrate the getDayOfYear() method:

Program 1:

// Java program to demonstrate
// ZonedDateTime.getDayOfYear() 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-year field
        int value = zoneddatetime.getDayOfYear();

        // print result
        System.out.println("day-of-year: " + value);
    }
}

Output:

day-of-year: 340

Program 2:

// Java program to demonstrate
// ZonedDateTime.getDayOfYear() method

import java.time.*;

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

        // create a ZonedDateTime object
        ZonedDateTime zoneddatetime
            = ZonedDateTime.parse(
                "2018-10-25T23:12:31.123+02:00[Europe/Paris]");

        // get day-of-year field
        int value = zoneddatetime.getDayOfYear();

        // print result
        System.out.println("day-of-year: " + value);
    }
}

Output:

day-of-year: 298
