a collection of Vehicles

Hallo i have a three classes , Abstract class Vehicle , concrete subclass of Vehicle Car and the Depot class(Vehicles Database) - i have an Gui with the name DepotAdmin with a private method SetupDepot which is where a depot is setup and at least 10 Vehicles are added to the depot .

my question is what is the best way to store those Vehicles in the Depot class , at the moment i am using arrayList , if i create car from car class and put it the Depot would be ok , or it will be better to use arrays ?

Thanks

which collections will "be better" depends on your needs. do you need no duplicates, fast iteration, fast deleting, sorting etc. in general an arraylist is ok, but tell if you have some special requirements.

ok i will write some more info so you understand better . i have some more classes the concrete subclass of car which is rentableCar and rentablecar implements the interface rentable and a Date class .Cos of the Vehicle being abstract all of the fields are transferred to car and all the fields are transfered again to rentablecar All of the dates are created from the date class
The depot class has two fields Depot Name and A collection of Vehicles where at the moment i have this private arrayList <Vehicle> vehicleList . The methods of depot are Add vehicle , find vehicle by make , remove vehicle , rent vehicle and return vehicle --

The only place the date of the return is recorded is in the rentablecar class so i need to connect the depot with the rentablecar class to get the rent Vehicle method working , can i create a method that adds 10 vehicles inside the depot class like a tester ?
