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:

Example 2:

Java




// Java program to demonstrate

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");
