- PurposeTo review abstract classes and polymorphismDirectionsThe total cost of a group of items at a grocery store is based on the sum of the individual product prices and the tax (which is 5.75%). Products that are considered “necessities” are not taxed, whereas products that are considered “luxuries” are. For this practice problem you will need to download Shopping Trip Starting Code.zip from Pilot.The Product class is abstract, and it has a method called getTotalPrice. Your task is to create two subclasses of Product: NecessaryProduct and LuxuryProduct and implement the getTotalPrice method in each of these classes appropriately. Then modify the driver program to instantiate four…You have to implement program that compares graduate students based on their ranks. The design of the program is given in the following UML diagram: • Student class: Base class that GradStudent extends. • GradStudent class: The objects from this class will be used for comparisons. • Rankable interface: Defines the implementation needed for comparison. GradStudent implements this interface. • Test class will be used to get student information from the user and demonstrate the comparison of students.Please written by hand solution In a particular factory, a shift supervisor is a salaried employee who supervises a shift. In addition, the shift supervisor earns a yearly bonus when their shift meets production goals. Write a private ShiftSupervisor class that is a subclass of the Employee class from problem 1. The ShiftSupervisor class should keep a data attribute for annual salary and data attribute for the annual production bonus that a shift supervisor has earned. Demonstrate the class by writing a program that uses a ShiftSupervisor object (create an object and display all the attributes). PYTHON ONLY
- For this problem you are to join the following classes into a hierarchy (use the UML diagrams from Module 2 to get started): Player - Super Class Archer - Subclass Barbarian - Subclass Cleric - Subclass Rogue - Subclass Warlock - Subclass If the parent class has the same attributes as the sub class then you can remove those attributes from the subclass. If the class is new for this module, please come up with 2 unique attributes of your choice, and 1 piece of functionality. If the sub classes are shown on the same level, then they share a parent class.Problem B Now we are going to use the design pattern for collecting objects. We are going to create two classes, a class AmazonOrder that models Amazon orders and a class Item that models items in Amazon orders. An item has a name and a price, and the name is unique. The Item class has a constructor that takes name and price, in that order. The class also has getters and setters for the instance variables. This is the design pattern for managing properties of objects. The setName() method should do nothing if the parameter is the empty string, and the setPrice() method should do nothing if the parameter is not positive. The class also has a toString() method that returns a string representation for the item in the format “Item[Name:iPad,Price:399.99]”. For simplicity, we assume an Amazon order can have at most 5 items, and class AmazonOrder has two instance variables, an array of Item with a length of 5 and an integer numOfItems to keep track of the number of items in the…Q1 is in picture do the q2 by watching q1 Q2 Your code must ensure that all the relevant classes Seller, Dealer, Buyer, and distinct classesAnimal and Invoice implement a common method for maintaining the finances. Details of theclasses can be seen in Table 1. Explain with proper syntax as to how this can be achieved usingobject-oriented programming, highlighting the changes you will need to make in the classdeclarations in Question 1. 2. Write Java code that implements the method for each class with the following details: a. The method for the Animal class calculates the price of the animal given the weightand price per kg of the animal.b. The method for the Dealer class calculates the commission earned by the dealer. Adealer may charge a certain percentage commission on the sale price of the Animal.c. The profit earned by the seller given a certain profit rate on the price of the animalcalculated in the Animal class. Sales Tax is deducted at the rate of 17% on the profitearned. The…
- T/F1. However, implementation classes may be extended, but interface classes cannot.The Critter class is a base class with some basic functionality for running simulations of different kinds of critters. Critters can move, act, and remember their history. A typical simulation contains a number of critters of different types. In each step of the simulation, the act member function will be called on each critter. Define a class Sloth derived from Critter that simulates a sloth. Sloths alternate between eating and sleeping. Add the word "eat" or "sleep" to the history each time the act function is called. The implementation of the Critter class is not shown. Complete the following file: sloth_Tester.cpp #include <iostream>using namespace std; #include "critter.h" /**A sloth eats and sleeps.*/class Sloth : public Critter{public:Sloth();. . .private:. . .}; Sloth::Sloth(){. . .} void Sloth::act(){if (...) {add_history("eat");...}else{add_history("sleep");... }} int main(){Sloth sloth;sloth.act();cout << sloth.get_history() << endl;cout <<…Suppose that class Child extends class Parent, and that Parent does not explicitly extend another class.

The Shapes class has only the calcArea() method. From Shapes, create three derived classes named Circle, Square and RightTriangle. Each of the three should have data members used to calculate the area of its shape. Define the method calcArea() for each of the three shapes. Each of the three shapes should also have appropriate constructors. Not required, but create a class with the main() method to test the classes created above.
