how can i add a zero if i had 61 seconds:it shows up as 1:1it should be 1:01thanks for the help, i did it a much harder way than you gave me for some stupid reason.

String time = (songLength/60)+":"+ (songLength%60);

if (songLength%60 < 10)

time = (songLength/60)+":"+ "0" + (songLength%60);

return time;

i got it all right there, thanks for the help

String DATE_FORMAT = "dd/MM/yyyy HH:mm:ss"; //for example

// TODO Auto-generated method stub

Calendar calendar = Calendar.getInstance();

calendar.set(Calendar.SECOND, calendar.get(Calendar.MINUTE)+500);

System.out.println(calendar.get(Calendar.MINUTE));

Date customDate = calendar.getTime();

SimpleDateFormat sdf = new SimpleDateFormat(DATE_FORMAT);

//System.out.println(customDate);//you can format this date

System.out.println(sdf.format(customDate));

This can be simplified using a Java 1.5 feature

String formattedMinutes = String.format("%d:%02d", minutes / 60, minutes % 60);

You can make that a one-liner:String format(int seconds) {

return (seconds/60)+((seconds%60)<10?":0":":")+(seconds%60);

}

I have a real problem with this approach. A number of minutes are not a date. They only become a date when relative to some point in time and your approach uses 1st Jan 1970. Since this approach uses SimpleDateFormat which have a built in time zone, the approach will fail for time differences that involve daylight saving and Leap years.
