Below are the examples to illustrate the dateYearDay() method:
Example 1:

Java

// Java program to demonstrate
// dateYearDay() method

import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;

public class GFG {
    public static void main(String[] argv)
    {
        try {
            // creating and initializing HijrahDate Object
            HijrahDate hidate = HijrahDate.now();

            // getting HijrahChronology used in HijrahDate
            HijrahChronology crono = hidate.getChronology();

            // getting HijrahDate for the
            // given date and year field
            // by using dateYearDay() method
            HijrahDate date = crono.dateYearDay(1440, 24);

            // display the result
            System.out.println("HijrahDate is: " + date);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can "
                               + "not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}

Output:

HijrahDate is: Hijrah-umalqura AH 1440-01-24

Example 2:

Java

// Java program to demonstrate
// dateYearDay() method

import java.util.*;
import java.io.*;
import java.time.*;
import java.time.chrono.*;

public class GFG {
    public static void main(String[] argv)
    {
        try {
            // creating and initializing HijrahDate Object
            HijrahDate hidate = HijrahDate.now();

            // getting HijrahChronology used in HijrahDate
            HijrahChronology crono = hidate.getChronology();

            // getting HijrahDate for the
            // given date and year field
            // by using dateYearDay() method
            HijrahDate date = crono.dateYearDay(2019, 24);

            // display the result
            System.out.println("HijrahDate is: " + date);
        }
        catch (DateTimeException e) {
            System.out.println("passed parameter can "
                               + "not form a date");
            System.out.println("Exception thrown: " + e);
        }
    }
}

Output:

passed parameter can not form a date
Exception thrown: java.time.DateTimeException: Invalid Hijrah date, year: 2019, month: 1
