The getDayOfYear() method of an LocalDateTime class is used to return the day-of-year field. This method returns an integer value ranging from 1 to 365 (366 for a leap year), i.e. the Days of a years.
Syntax:
public int getDayOfYear()
Parameter: This method does not accept any parameter.
Returns: This method returns an integer value which represents the day-of-year and it ranges from 1 to 365 (366 for a leap year).
Below programs illustrate the LocalDateTime.getDayOfYear() method:
Program 1:
// Java program to demonstrate// LocalDateTime.getDayOfYear() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a LocalDateTime Object        LocalDateTime local            = LocalDateTime.parse("2018-12-03T12:39:10");          // get DayOfYear        int dayOfYear = local.getDayOfYear();          // print result        System.out.println("DayOfYear: "                           + dayOfYear);    }} |
Output:
DayOfYear: 337
Program 2:
// Java program to demonstrate// LocalDateTime.getDayOfYear() method  import java.time.*;  public class GFG {    public static void main(String[] args)    {          // create a LocalDateTime Object        LocalDateTime local            = LocalDateTime.parse("2019-01-28T22:29:10");          // get DayOfYear        int dayOfYear = local.getDayOfYear();          // print result        System.out.println("DayOfYear: "                           + dayOfYear);    }} |
Output:
DayOfYear: 28
