- I need help in coding these two classes(dorm and room) in JAVA from the following information-> *A dormitory has a name and has several rooms. When a dormitory is built, the name and the number of rooms should be provided. In some cases, the maximum capacity of the rooms is also provided. If there is no maximum capacity set, each room can accommodate at most 6 guests. *The rooms are then automatically created and added to the dormitory, numbered from 1, 2, 3, and so on, representing the room number. Once the room number is assigned to the created room, this information cannot be edited anymore. *The dormitory can accept guests into a given room number. Each guest has a name and nationality. If the capacity is full or an invalid room number is provided, the guest will not be added and this method returns false. Otherwise, this method returns true. *The dormitory also has a method to return the guests in a given room number. If an invalid room number is provided, the method will…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. The…arrow_forwardWrite a complete program for the description given below. Consider a Billing class that implements an interface Payable having a method getTotalPayment Amount(). Besides this, you have a Doctor class with private instance variables (docID, docName, and docFee) and a public getDoc() method, Patient class with private instance variables (pName, pID. pDisease), Medicine class with private instance variables (medID, medName, medQty, medPrice), and Medical Test class with private instance variables (testID, testName, testPrice). Each of these classes has the toString() method to display the information of its object. The Billing class is having "Has A" relationship with the other four classes (Doctor, Patient, Medicine, and MedicalTest) mentioned above. The getPayment Amount() method of Billing class returns the total billing amount that includes doc fee, medicine cost, and medical test fee that a patient has to pay. After implementing these classes, you are required to do the following in…arrow_forward
- We have a parking office class for an object-oriented parking management system using java Add (implement )a function to the Parking Office class to return a collection of customer ids (getCustomerIds) 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 getcustomerID function as mentioned above Explain the code you wrote with a few wordsarrow_forwardCan you implement the Derived Class Parameterized constructor? A solution is placed in the "solution" section to help you, but we would suggest you try to solve it on your own first. Implement the constructor Dell(String name) of the Derived Class Dell which takes a string, name. We have already implemented the Base Class Laptop with the member function getName() and a parameterized constructor. Input# Laptop name is being passed through the parameterized constructor. Output# getName() method is returing Laptop name. Sample Input# Dell dell = new Dell("Dell Inspiron"); Sample Output# "Dell Inspiron"arrow_forwardImagine you have two classes: Employee (which represents being an employee) and Ninja (which represents being a Ninja). 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). By creating only one interface and only one class (NinjaEmployee), show how you can do this without having to copy method implementation code from either of the original classes.arrow_forward
- Consider the following class Date, which represents a date using three ints for month, day and year: class Date { private: int month; int day; int year; public: Date() { month = day = year = 0; } Date(int m, int d, int y) { month = m; day = d; year = y; } bool operator==(Date); bool operator<(Date); }; Write an implementation for both overloaded operators. == should return true if the Date objects are equivalent and false if not. < should return true if the Date of the calling object (left object) comes before the parameter Date object (right object) and false if not. You may assume that all objects of class Date are valid, i.e. month is between 1 and 12, inclusive; day contains an appropriate day for the given month, and year can be anything. You do not need to demonstrate calling these operators.arrow_forwardHow do I take a long number input, validate the input as a long number and then subsequently use it in a different class? Basically, I want to input and validate a 15-16 digit long number (to exclude string and float), fetch it again to validate it with a different set of conditions in a different or subsequent class.arrow_forwardWrite a Java program with least two classes. Using the circle object to represent it. The class must have at least one (non-static) setter method and one (non-static) getter method. Implement at least on test that invokes the setter and getter method and the corresponding getter method so that the value out == the the value inarrow_forward
- 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_forwardWe have a parking office class for an object-oriented parking management system using java Add (implement )a method to the Parking Office c to return a collection of customer ids (getCustomerIds) using java I have attached two class diagrams with definitions of all related classes in our system (i.e car, customer, .....).
