Convert seconds value to hours minutes seconds?

Question

Is it necessary to use a BigDecimal? If you don't have to, I'd use an int or long for seconds, and it would simplify things a little bit:

hours = totalSecs / 3600;
minutes = (totalSecs % 3600) / 60;
seconds = totalSecs % 60;

timeString = String.format("%02d:%02d:%02d", hours, minutes, seconds);

You might want to pad each to make sure they're two digit values(or whatever) in the string, though.

DateUtils.formatElapsedTime(long), formats an elapsed time in the form "MM:SS" or "H:MM:SS" . It returns the String you are looking for. You can find the documentation here

You should have more luck with

hours = roundThreeCalc.divide(var3600, BigDecimal.ROUND_FLOOR);
myremainder = roundThreeCalc.remainder(var3600);
minutes = myremainder.divide(var60, BigDecimal.ROUND_FLOOR);
seconds = myremainder.remainder(var60);

This will drop the decimal values after each division.

Edit: If that didn't work, try this. (I just wrote and tested it)

public static int[] splitToComponentTimes(BigDecimal biggy)
{
    long longVal = biggy.longValue();
    int hours = (int) longVal / 3600;
    int remainder = (int) longVal - hours * 3600;
    int mins = remainder / 60;
    remainder = remainder - mins * 60;
    int secs = remainder;

    int[] ints = {hours , mins , secs};
    return ints;
}

Here is the working code:

private String getDurationString(int seconds) {

    int hours = seconds / 3600;
    int minutes = (seconds % 3600) / 60;
    seconds = seconds % 60;

    return twoDigitString(hours) + " : " + twoDigitString(minutes) + " : " + twoDigitString(seconds);
}

private String twoDigitString(int number) {

    if (number == 0) {
        return "00";
    }

    if (number / 10 == 0) {
        return "0" + number;
    }

    return String.valueOf(number);
}

Something really helpful in Java 8

import java.time.LocalTime;

private String ConvertSecondToHHMMSSString(int nSecondTime) {
    return LocalTime.MIN.plusSeconds(nSecondTime).toString();
}
