You should have a class: Year, which has twelve instances of a class Month, which has x instances of class Day. in class Day you keep a List or Set of Appointments.

All you have so far is GUI. You'll need actual logic to go with it, too.

If you need to add events, then the obvious way to start is to create an Event class. It would have start date/time, and date/time, title, location etc as instance variables, with the usual getters and setters and a constructors. You can use GregorianCalendar instances for the start and end dates if you want (I don't agree with stultuske in this particular case).

Now you can do the rest in simple sub-tasks:

Create a simple GUI form to enter the data for a new Event.
Create a list of Events.
Define methods to search the list - eg get the Event(s) for a specified date
Use that to get the events for each day in you Calendar and display them

James ,, the list of events which I have to create >>is it a vector ?? or an array of list ?? or it's just an array of strings ??
I didn't get how can I take the saved event for the day ??
could U tell me more about that ??
the thing that I have to do is that whenever I clicked on any day in the calander (I've created the days as buttons)>>it should show me the events of that day in a textArea which I've put under the calendar in the same frame !
and also >>in your opinion which is easier ! to make a button (addEvent(it should give me the frame that I can insert the event))or once I click to a certain day it should popup a frame (and inside that frame I can insert the event ) but it still I can't do the get event !I don't know how and where can I make it !
and Thank U so much ^_^

All of that actually depends on your needs and requirements.

ok >>so I want to make a button (addevent) and when I click on it >>it should give me a frame where can I insert the event >>so in that frame (there is 2 textFields for location and title and there is 3 combo boxes >> one for days one for years and one for monthes )!
and also 2 textFields for start and end time !
consider that the user entered all these things !!
but actually >>I didn't know where should I save all these information of that event in order to put them in the text area and also whenever I click on that day it should give me the events on that day !! and also I have to highlight the days which have an event !
I don't know how to do that !!
could U help me plz ?! :(

Create the Event class first.
The create a List<Event>. It doesn't matter what kind of List it is (ArrayList, LinkedList, Vector etc).

ok thank U ^_^ I'll try that >> and I hope it will work :/
