Convert Seconds into HH:MM:SS in java?

Below are the methods to convert seconds into minute seconds format...


int day = (int)TimeUnit.SECONDS.toDays(seconds);      
long hours = TimeUnit.SECONDS.toHours(seconds) - (day *24);
long minute = TimeUnit.SECONDS.toMinutes(seconds) - (TimeUnit.SECONDS.toHours(seconds)* 60);
long second = TimeUnit.SECONDS.toSeconds(seconds) - (TimeUnit.SECONDS.toMinutes(seconds) *60);
 System.out.println("Random Element "+minute+":"+second);

OR 

public static void calculateTime(long seconds) {
   int day = (int) TimeUnit.SECONDS.toDays(seconds);
   long hours = TimeUnit.SECONDS.toHours(seconds) -
                TimeUnit.DAYS.toHours(day);
   long minute = TimeUnit.SECONDS.toMinutes(seconds) -
                 TimeUnit.DAYS.toMinutes(day) -
                 TimeUnit.HOURS.toMinutes(hours);
   long second = TimeUnit.SECONDS.toSeconds(seconds) -
                 TimeUnit.DAYS.toSeconds(day) -
                 TimeUnit.HOURS.toSeconds(hours) -
                 TimeUnit.MINUTES.toSeconds(minute);
   System.out.println("Day " + day + " Hour " + hours + " Minute " + minute + " Seconds " + second);
}
