        System.out.println(GregorianCalendar.AD);
        System.out.println(GregorianCalendar.ALL_STYLES);

        System.out.println(GregorianCalendar.BC);
        System.out.println(GregorianCalendar.AM);

        System.out.println(GregorianCalendar.AM_PM);
        System.out.println(GregorianCalendar.APRIL);

    }
}
