Design a small app to convert from Hijri to Gregorian and vi

Design a small app to convert from Hijri to Gregorian and vice versa (keep it simple as if on input 2016 you get 1437).

Solution

import java.time.chrono.HijrahChronology;

import java.time.chrono.HijrahDate;

import java.time.chrono.IsoChronology;

/**

*Java program

*/

public class Main {

    public static void main(String[] args) {

        HijrahDate date = HijrahChronology.INSTANCE.date(1437,05,27);

        System.out.println(date);

        System.out.println(IsoChronology.INSTANCE.date(date));

    }

}
