Look at the SimpleDateFormat class.

Look at Calendar.getTimeInMillis() method. It provides a number of
milliseconds since January 1, 1970.
You should code something like :
static int MILLIS_IN_DAY = 1000 * 60 * 60 * 24;
int diffInMillis = cal1.getTimeInMillis() - cal2.getTimeInMillis();
double diffInDays = diffInMillis / MILLIS_IN_DAY;
