This implementation makes so much more sense, however, the LineItem class I have to go off of is a tad bit different. How would it look given the following?

- IN C++ Implement a class Car with the following properties. A car has a certain fuel efficiency (measured in miles/gallon or liters/km—pick one) and a certain amount of fuel in the gas tank. The efficiency is specified in the constructor, and the initial fuel level is 0. Provide another parameterized constructor which takes both efficiency and fuel as parameters. Also supply methods getGasInTank, returning the current amount of gasoline in the fuel tank. getEfficiency() return the efficiency of car. setGasInTank(double fuel), to add gasoline to the fuel tank. setEfficiency(double efficiency) Supply a method Drive () that simulates driving the car for a certain distance, reducing the amount of gasoline in the fuel tank according to its efficiency. Sample usage: Car myHybrid (50); // 50 miles per gallon myHybrid.addGas(20); // Tank 20 gallons myHybrid.Drive(100); // Drive 100 miles double gasLeft = myHybrid.getGasInTank(); // Get gas remaining in tank Supply a main method that tests…arrow_forwardFor 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.

- We have a parking office class for an object-oriented parking management system using java Add(implement) a method to the Parking Office class to return the collection of permit ids for a specific customer (getPermitIds(Customer)) using java I have attached two class diagrams with definitions of all related classes in our system (i.e car, customer, .....). N.B. Parking office methods in the class definition like register, getcustomer and addcharge have already been implemented, we just need an additional getPermitIds(Customer) method as mentioned above Explain your code in a few words Important- We have a method to return a collection of permit ids (getPermitIds), what we need is a method to return the collection of permit ids for a specific customer (getPermitIds(Customer))arrow_forwardIs it possible for a class that has no abstract methods to be defined as abstract?

An Employee has both state and behaviour; a Ninja has only behaviour. You need to represent an employee who is also a ninja (a common problem in the real world).

There is a maximum capacity to the number of gold coins a leprechaun can store at any given time (the pot they store them in can only hold so many). The pot also holds a current amount. What does the LeprechaunGold object need to remember? Those are the instance variables. Provide a constructor that takes the maximum capacity as a parameter. The constructor initializes the instance variables (two of them). Provide methods public int getCapacity() - gets the maximum capacity public int getAmount() - gets the number of coins in the pot public void donate(int coins) - simulates making a donation public void save(int coins) - simulates adding more coins to the potarrow_forwardA java program, with a class Rectangle with attributes length and width , each of which defaults to 2.
