how can I format a date in java with "ff"?

Question

I'm trying to print a date with the following format:

"HHmmssff" 

I'm using SimpleDateFormatter. It fails because it can't recognize "ff". Is there another formatter that can? Or any other way to do it?

Answer 1

If you are looking for printing second in fractions (milliseconds), this example will be helpful.

public class DateFormatter {
    public static void main(String[] args) {
        Date date = Calendar.getInstance().getTime();
        DateFormat formatter = new SimpleDateFormat("EEEE, dd MMMM yyyy, hh:mm:ss.SSS a");
        String today = formatter.format(date);
        System.out.println("Today : " + today);
    }
}

Output: Today : Tuesday, 24 May 2011, 07:23:30.627 PM

You see SSS in the formatter returns fractions of seconds for you.
