            // used in LocalDate
            JapaneseChronology crono
                = hidate.getChronology();
  
            // getting JapaneseEra for the
            // given integer value
            // by using eraOf() method
            JapaneseEra era = crono.eraOf(0);
  
            // display the result
            System.out.println(
                "JapaneseEra is: "
