I've got a Vector, containing Appointment objects.
Each Appointment object contains date, start time, end time and description.
Date Start Time End
21/02/2003 09:00 10:00
21/02/2003 07:00 08:00
I need to sort the appointment according to date, n in the example above, if the dates are the same, i need to sort according to the start time in ascending order.
How can i implement this using SortedSet?
