Answer 1

DateTimeUtils obj = new DateTimeUtils(); SimpleDateFormat simpleDateFormat = new SimpleDateFormat("dd/M/yyyy hh:mm:ss");  try {     Date date1 = simpleDateFormat.parse("10/10/2013 11:30:10");     Date date2 = simpleDateFormat.parse("13/10/2013 20:35:55");      obj.printDifference(date1, date2);  } catch (ParseException e) {     e.printStackTrace(); }  //1 minute = 60 seconds //1 hour = 60 x 60 = 3600 //1 day = 3600 x 24 = 86400 public void printDifference(Date startDate, Date endDate) {      //milliseconds     long different = endDate.getTime() - startDate.getTime();      System.out.println("startDate : " + startDate);     System.out.println("endDate : "+ endDate);     System.out.println("different : " + different);      long secondsInMilli = 1000;     long minutesInMilli = secondsInMilli * 60;     long hoursInMilli = minutesInMilli * 60;     long daysInMilli = hoursInMilli * 24;      long elapsedDays = different / daysInMilli;     different = different % daysInMilli;      long elapsedHours = different / hoursInMilli;     different = different % hoursInMilli;      long elapsedMinutes = different / minutesInMilli;     different = different % minutesInMilli;      long elapsedSeconds = different / secondsInMilli;      System.out.printf(         "%d days, %d hours, %d minutes, %d seconds%n",          elapsedDays, elapsedHours, elapsedMinutes, elapsedSeconds); } 

out put is :

startDate : Thu Oct 10 11:30:10 SGT 2013 endDate : Sun Oct 13 20:35:55 SGT 2013 different : 291945000 3 days, 9 hours, 5 minutes, 45 seconds
