If you need to use standard java classes then Calendar class is the best choice here. http://developer.android.com/reference/java/util/Calendar.html

Simple code:

        Calendar nextDayCal = Calendar.getInstance();
        nextDayCal.add(Calendar.DAY_OF_YEAR, 1);
        nextDayCal.set(Calendar.MILLISECOND, 0);
        nextDayCal.set(Calendar.SECOND, 0);
        nextDayCal.set(Calendar.MINUTE, 0);
        nextDayCal.set(Calendar.HOUR_OF_DAY, 0);

        Calendar nowCal = Calendar.getInstance();

        int hourDif = nextDayCal.get(Calendar.HOUR_OF_DAY) - nowCal.get(Calendar.HOUR_OF_DAY);
