            JapaneseDate hidate 
                = JapaneseDate.now();

            // 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:"
                + era); 
        } 
        catch (DateTimeException e) { 
            System.out.println(

            // used in LocalDate 
            JapaneseChronology crono 
                = hidate.getChronology(); 
  
            // getting JapaneseEra for the 
            // given integer value 
            // by using eraOf() method 
            JapaneseEra era = crono.eraOf(2); 
  
            // display the result 
            System.out.println("JapaneseEra is:"
                               + era); 
        } 
        catch (DateTimeException e) { 
            System.out.println( 
                "JapaneseEra is invalid");
