Representation of an object depends heavily on its use. Below is the UML diagram of a Car class that will be used by a car dealer. For each car, our dealer stores the following information: (1) the date (availableSince) this car was placed on the lot, (2) a Boolean variable (isNew) indicating whether the car is new or second-hand, (3) the price tag on a new model (newPrice), and (4) a unique identifier (carID). The dealer determines the selling price of a car using the following function: if the car is new, it has to be sold at the newPrice. Otherwise, the price of a (second-hand) car is reduced in proportion to the duration of time the car stayed on the lot. At Date d, this price is calculated as depreciated Price(d)=1/millisOnLot(d.availableSciene)
