Example 1:

Java

// Java program to demonstrate
// date() 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, month and year field
            // by using date() method
            HijrahDate date = crono.date(1440, 05, 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 1440-05-24

            HijrahDate hidate = HijrahDate.now();

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

            // getting HijrahDate for the
            // given date, month and year field
            // by using date() method
            HijrahDate date = crono.date(2019, 05, 24);

            // display the result
            System.out.println("HijrahDate is: " + date);
        }
        catch (DateTimeException e) {
            System.out.println("Exception thrown: " + e);
        }
    }
}

Output:

Exception thrown: java.time.DateTimeException: Invalid Hijrah date, year: 2019, month: 5
