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
