Android difference between Two Dates


I have two date like:

String date_1="yyyyMMddHHmmss";
String date_2="yyyyMMddHHmmss";

I want to print the difference like:

2d 3h 45m

How can I do that? Thanks!


Solution

  • 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
