LocalDate Class lengthOfYear() method

• lengthOfYear() method is available in java.time package.
• lengthOfYear() method is used to get the length of the year represented by this LocalDate.
  length of year = No. of days in a year [i.e. 1 to 365 (for a non-leap year) or 366 (for leap year)].
• lengthOfYear() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• lengthOfYear() method does not throw an exception at the time of returning length.

Syntax:

    public int lengthOfYear();

Parameter(s):

• None

Return value:

The return type of this method is int, it returns the length of year denoted by this object.

Example:

// Java program to demonstrate the example 
// of int lengthOfYear() method of LocalDate

import java.time.*;

public class LengthOfYearOfLocalDate {
    public static void main(String args[]) {
        // Instantiates three LocalDate
        LocalDate l_da1 = LocalDate.parse("2007-04-04");
        LocalDate l_da2 = LocalDate.now();
        LocalDate l_da3 = LocalDate.of(2008, Month.FEBRUARY, 06);

        // Display l_da1,l_da2 and l_da3
        System.out.println("LocalDate l_da1,l_da2 and l_da3: ");
        System.out.println("l_da1: " + l_da1);
        System.out.println("l_da2: " + l_da2);
        System.out.println("l_da3: " + l_da3);

        System.out.println();

        // Here, this method returns the length
        // of year represented by this date
        // l_da1 i.e. here l_da1 = "2007-04-04"
        // then number of days in the year 2007 is
        // 365 i.e. length = 365
        int length = l_da1.lengthOfYear();

        // Display length
        System.out.println("l_da1.lengthOfYear(): " + length);

        // Here, this method returns the length of
        // year represented by this date
        // l_da2 i.e. here l_da2 = "2020-05-08" 
        // then number of days in the year 2020
        // is 366 i.e. length = 366
        length = l_da2.lengthOfYear();

        // Display length
        System.out.println("l_da2.lengthOfYear(): " + length);

        // Here, this method returns the length of
        // year represented by this date
        // l_da3 i.e. here l_da3 = "2008-02-06" 
        // then number of days in the year 2008 
        // is 366 i.e. length = 366
        length = l_da3.lengthOfYear();

        // Display length
        System.out.println("l_da3.lengthOfYear(): " + length);
    }
}

Output

LocalDate l_da1,l_da2 and l_da3: 
l_da1: 2007-04-04
l_da2: 2020-06-02
l_da3: 2008-02-06

l_da1.lengthOfYear(): 365
l_da2.lengthOfYear(): 366
l_da3.lengthOfYear(): 366
