Question

For a parking management system, use the Observer pattern to implement this interaction using Java and implement the three classes mentioned below. Implement a ParkingObserver that has the role of the Observer. The Observable classes (Subjects) will be the ParkingLots. It would be helpful if the notify method in the subjects (and update method in the observers) took a parameter, perhaps an object of type ParkingEvent, which could have fields including the lot, timeIn, timeOut (if relevant), and permit. The ParkingObserver should register with each ParkingLot and receive the messages. Once a car enters (in an entry-scan only lot) or leaves (in an entry-scan and exit-scan lot), then the ParkingObserver will be updated, and then can register the charge with the parking system via the TransactionManager’s park() method. Based on these requirements you should implement three actor classes in this interaction using java: TransactionManager, ParkingObserver and ParkingLot. 1. The…

Why is the ability to redefine a method important in object-oriented programming?Choose all options that apply.(a) Because it allows us to add extra work to a method.(b) Because it allows us to introduce abstract methods that are redefined as concrete methods.(c) Because it allows us to provide a more accurate or faster definition in a subclass.(d) Because it allows us to disable a method in a subclass.(e) Because it allows us to change the meaning of a method.
