You can use SimpleDateFormat class to give a complete date info:

DateFormat df = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
        Date startDate = df.parse("2016-05-24 17:50:10");
        Date endDate = df.parse("2016-05-25 19:05:15");
        long diff = endDate.getTime() - startDate.getTime();

        int timeInSeconds = (int) (diff / 1000);
        int hours, minutes, seconds;
        hours = timeInSeconds / 3600;
        timeInSeconds = timeInSeconds - (hours * 3600);
        minutes = timeInSeconds / 60;
        timeInSeconds = timeInSeconds - (minutes * 60);
        seconds = timeInSeconds;

        System.out.println(String.format("%d:%d':%d\"", hours, minutes, seconds));
