Solution :

One can also use the TimeUnit class

One could define as following

private static final String FORMAT = "%02d:%02d:%02d";
Also can have a method like following:

public static String parseDateTime(long milliseconds) {
      return String.format(FORMAT,
              TimeUnit.MILLISECONDS.toMinutes(milliseconds) - TimeUnit.HOURS.toMinutes(
              TimeUnit.MILLISECONDS.toSeconds(milliseconds) - TimeUnit.MINUTES.toSeconds(
