How do you format the day of the month to say “11th”, “21st” or “23rd” (ordinal indicator)?

Question

I know this will give me the day of the month as a number (11, 21, 23):

SimpleDateFormat formatDayOfMonth = new Simple         


        

Answer 1

private String getCurrentDateInSpecificFormat(Calendar currentCalDate) {
    String dayNumberSuffix = getDayNumberSuffix(currentCalDate.get(Calendar.DAY_OF_MONTH));
    DateFormat dateFormat = new SimpleDateFormat(" d'" + dayNumberSuffix + "' MMMM yyyy");
    return dateFormat.format(currentCalDate.getTime());
}

private String getDayNumberSuffix(int day) {
    if (day >= 11 && day <= 13) {
        return "th";
    }
    switch (day % 10) {
    case 1:
        return "st";
    case 2:
        return "nd";
    case 3:
        return "rd";
    default:
        return "th";
    }
}
