public class GFG {
    public static void main(String[] args)
    {

        // create MonthDay object
        MonthDay lt
            = MonthDay.parse("--12-09");

        // apply query method of MonthDay class
        String value
            = lt.query(
                    TemporalQueries.chronology())
                  .toString();

        // print the result
        System.out.println("chronology value"
                           + " for MonthDay is "
                           + value);

    public static void main(String[] args)
    {

        // create MonthDay object
        MonthDay lt
            = MonthDay.parse("--12-07");

        // apply query method of MonthDay class
        // print the result
        System.out.println("offset value"
                           + " for MonthDay is "
                           + lt.query(
                                 TemporalQueries.offset()));
