The following code might be helpful:

public static void main(String[] args)

      {

            Scanner reader = new Scanner(System.in); 

            System.out.println("Enter two dates and time in the following format (yy/MM/dd HH:mm:ss) : ");

            String dateStart = reader.nextLine();

            String dateStop = reader.nextLine();

            reader.close();

           SimpleDateFormat format = new SimpleDateFormat("yy/MM/dd HH:mm:ss");

           java.util.Date d1 = null;

           java.util.Date d2 = null;

           try

          {

                  d1 =  format.parse(dateStart);

           }

          catch (java.text.ParseException e)

          {

                  e.printStackTrace();

           }

           try

           {

                  d2 =  format.parse(dateStop);

           }

           catch (java.text.ParseException e)

           {

                  e.printStackTrace();

           }

           long d = d2.getTime() - d1.getTime();

           long dS = d / 1000 % 60;

           long dM = d / (60 * 1000) % 60;

           long dH = d / (60 * 60 * 1000);

           long days=0;

           if (dH>24)

           {

            days = dH/24;

            dH = dH - (24*days);

          }

          System.out.println("The elapsed time is: "+days+" Days "+dH+" Hours "+dM+ " Minutes "+dS+" Seconds ");       

      }

}
