My Comparators all look something like:
class ReservationComparator implements Comparator<Reservation> {
> @Override
> public int compare(Reservation o1, Reservation o2) {
> return Integer.compare(o1.getReservationID(), o2.getReservationID());
> }
> }
Where Reservation.getReservationID() returns a simple "int" or
class BookingIDComparator implements Comparator<String> {
> @Override
> public int compare(String o1, String o2) {
> return Integer.compare(Integer.parseInt(o1), Integer.parseInt(o2));
> }
> }
Where I am comparing stringified ints. Actually the third instance is more
complex because the sorting criteria of the list-of-object looks at dates
and then ints.
class BookingComparator implements Comparator<Booking> {
> @Override
> public int compare(Booking o1, Booking o2) {
> int result = 0;
if ((result = o1.getTimeBookingStart().compareTo(
> o2.getTimeBookingStart())) == 0) {
> if ((result = o1.getTimeBookingEnd().compareTo(
> o2.getTimeBookingEnd())) == 0) {
> result = Integer.compare(o1.getBookingID(),
> o2.getBookingID());
> }
> }
> return result;
> }
> }
that is Date.compare, Date.compare then Integer.compare of two returned
ints.
