OOPs
In today's technology-driven world, computer programming skills are in high demand. The object-oriented programming (OOP) approach is very much useful while designing and maintaining software programs. Object-oriented programming (OOP) is a basic programming paradigm that almost every developer has used at some stage in their career.
Constructor
The easiest way to think of a constructor in object-oriented programming (OOP) languages is:
Derived classes can directly access what members of their base class?
private
public
protected
private and public
public and protected
protected and private
Step by step
Solved in 2 steps
- Create class employee with properties ID, name, salary, write accessor, mutator &constructor for the class. In main create three objects of class & find the employee with the highestsalary.Which type of class member is not visible to derived classes? 1. Private 2. Public 3. Protected 4. ReadOnly- Creates a class Teacher with two attributes: name and specialty. a. Add a constructor able to create a Teacher; b. Add the methods getName and getSpeciality; c. Add the method display able to display the attributes
- Build a class Sale with private member variablesdouble itemCost; // Cost of the itemdouble taxRate; // Sales tax rateand functionality mentioned below:● Write a default constructor to set the member variable itemCost to 0 andtaxRate to 0. ● Write a parameterized constructor that accepts the parameter for eachmemberSale( double cost, double rate) c++Create a base class called “Animal” which has two (2) class fields. The first field holds an integer “IDtag” for a number that a zoo uses to catalogue their animals and the second field holds a string called “species.”From the Animal class, derive two (2) classes. One is called “Bird” and the other “Reptile”. E.g. Species could be (for the Bird class) ostrich, dove, chicken etc. and (for the Reptile class) lizard, snake, bearded dragon etc.The Bird class has an additional class field called “colour” which holds the colour of the birds feathers (int – 1=grey, 2=white, 3=black). The reptile class has an additional class field called “bloodTemp” which hold the reptile’s temperature of their blood (double).You need to instantiate two (2) objects. The bird object will be called “brd” and the reptile object called “rept.”Input values for the bird’s IDtag, species and feather colour (int) and for the reptile’s IDtag number, species and bloodTemp. Override the Animal class’s input and output…Given the following code for the base class Ship write another class that inherits from Ship called SpaceShip. Spaceship should have a field to store forwardLasers(an integer) and aftMineDispensers (another integer). You should provide a constructor that includes forwardLasers as an argument. You should have another constructor that includes both forwardLasers and aftMineDispensers as arguments. You should provide appropriate accessors and mutators. You should include a toString() method that prints out the forwardLasers and aftMineDispensers as well as the information from the super class toString(). Here is the code for the base class Ship. public class Ship { private String name; // Ship name private String yearBuilt; // Year it was built public Ship(String n, String y) { name = n; yearBuilt = y; } public void setName(String n) { name = n; } public void setYearBuilt(String y) { yearBuilt = y; } public String getName() { return…
- NewspaperSubscriber class- create an abstract class named NewspaperSubscriber with attributes to contain the subscriber’s street address and the subscription rate. Include get and set methods for both these attributes. The set method for the rate is abstract. The setAddress method must prompt the user to enter the subscriber’s address through the use of a dialog box. Create a constructor for the base class. Create a toString() method that concaternates and returns the subscriber’s street address and rate for display. Create 3 child classes named SevenDaySubscriber, Weekday Subscriber, and Weekend Subscriber. Each child class has an additional attribute called subType, which is a String, that will store the type of newspaper subscription. Create a setType method that will set the type of subscriber as follows: “Seven Day”, “Weekday”, or“Weekend”. Create a setRate method for each child class that sets the rate as follows: a SevenDaysubscriber pays R18.00 per week for his newspapers, a…Parking Ticket SimulatorFor this assignment you will design a set of classes that work together to simulate apolice officer issuing a parking ticket. The classes you should design are:• The Parkedcar Class: This class should simulate a parked car. The class's respon-sibilities are:To know the car's make, model, color, license number, and the number of min-utes that the car has been parkedThe BarkingMeter Class: This class should simulate a parking meter. The class'sonly responsibility is:- To know the number of minutes of parking time that has been purchased• The ParkingTicket Class: This class should simulate a parking ticket. The class'sresponsibilities areTo report the make, model, color, and license number of the illegally parked carTo report the amount of the fine, which is $2S for the first hour or part of anhour that the car is illegally parked, plus $10 for every additional hour or part ofan hour that the car is illegally parkedTo report the name and badge number of the police…Q2. Write a class Bank that has the following data members –Account Holder name (ah_name[]) –Account number (ac_number) •Must unique, system generates automatically, and must starting from 100 (Hints: Use another static variable and assign that variable to ac_number) –Balance in the account (ac_balance) •The class has the following member functions –A constructor to initialize the data members –Input() to takes name from the user –Deposit(parameter) to deposits balance in the account •Must accept parameter (The amount to deposit) –Withdraw(parameter) to withdraws balance after checking •Must accept parameter (The amount to withdraw) –Display() to show the name, account number, and balance
- Creates a class called Member with two integer x and y. a. Add a constructor able to create a Member object with tow integers and the default values 0,0; b. Add the methods setX and setY to modify the attributes x and y; c. Add the method display able to display the attributes,B elow for each class you find a UML and description of the public interface. Implementing the public interface as described is madatory. There's freedom on how to implement these classes.The private properties and private methods are under your control.. There are multiple ways of implementing all these classes. Feel free to add private properties and methods. For each object, it's mandatory to create a header file (.h), implementation file (.cpp) and a driver. Blank files are included. The header should have the class definition in it. The implementation file should contain the implementations of the methods laid out in the header fine. And finally the Driver should test/demonstrate all the features of the class. It's best to develop the driver as the class is being written. Check each section to see if there are added additional requirements for the driver. Two test suites are included so that work can be checked. It's important to implement the drivers to test and demonstrate…Create a classstudent which includes parameters roll_no, name and address and consider as super class.Then create sub class test with parameters marl1, mark2, mark3 and mark4. Then create another sub class result with parameters total_marks, percentage and grade. Apply multi level inheritance. Here Student class is the super class for test class and test class is super class of resultclass. Implement a java application in which obtain the details roll_no, name, address, marl1, mark2, mark3 and mark4 from user side andthen print total_marks, percentage and grade.Studentàtestàresult
