Answer 3

Calendar cal = new GregorianCalendar();
    
    // Get the components of the date
    int era = cal.get(Calendar.ERA);               // 0=BC, 1=AD
    int year = cal.get(Calendar.YEAR);             // 2002
    int month = cal.get(Calendar.MONTH);           // 0=Jan, 1=Feb, ...
    int day = cal.get(Calendar.DAY_OF_MONTH);      // 1...
    int dayOfWeek = cal.get(Calendar.DAY_OF_WEEK); // 1=Sunday, 2=Monday, ...
    int hour12 = cal.get(Calendar.HOUR);            // 0..11
    int hour24 = cal.get(Calendar.HOUR_OF_DAY);     // 0..23
    int min = cal.get(Calendar.MINUTE);             // 0..59
    int sec = cal.get(Calendar.SECOND);             // 0..59
    int ms = cal.get(Calendar.MILLISECOND);         // 0..999
    int ampm = cal.get(Calendar.AM_PM);             // 0=AM, 1=PM
