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:

- The ability to create classes with more specific attributes and methods that share the properties and methods of existing classes is referred to as: Abstraction Polymorphism Typecasting InheritanceInheritance Create a base class called Shape with two final variables: PI and shapeType. PI should be set to 3.14159 and shapeType should be a String that indicates the type of shape. Create a subclass called Circle that extends Shape. Circle should have an instance variable called radius and a constructor that initializes radius. Override the toString() method to display the details of the circle, including its shape type, radius, and area. Create another subclass called Rectangle that extends Shape. Rectangle should have two instance variables called length and width, and a constructor that initializes length and width. Override the toString() method to display the details of the rectangle, including its shape type, length, width, and area. In the main method, create objects of Circle and Rectangle and call their toString() methods to demonstrate inheritance and the use of final variables.Create a class called ship that incorporates a ship’s serial number and location. Create another class angle which has two variables latitude and longitude. A member function of the ship class should get a position from the user and store it. Create object that should report the serial number and position. Write a main () program that creates three ships, asks the user to input the position of each, and then displays each ship’s serial number and position.Identify all the classes implement inheritance between them. (language cpp)
- Java Object Oriented Programming Create a Shape class that shall have color and filled instance variables of enum Color and boolean type. The filled boolean variable shall show, whether the shape is filled (colored). The enum Color shall be defined within the class having 4 color names (choose any four). Also define getArea and getPerimeter method in Shape class, both shall return 0. Create Rectangle class with length and width attributes and a Circle class with radius attribute, of type double. Properly encapsulate all fields. Circle and Rectangle shall extend Shape class and override getArea and getPerimters methods as per its type and specific formula. In Test class, create an object of Rectangle and Circle, by initializing all attributes in constructor and print both shapes' area and perimters. In Test class, define a static method with following signature, public static void printEachShapeCount(Shape... shapes) As you know, the parent type variable can hold the…Farrell, Joyce. Microsoft Visual C#: An Introduction to Object-Oriented Programming (p. 479). Kindle Edition. 9. Write a program named SalespersonDemo that instantiates objects using classes named RealEstateSalesperson and GirlScout. Demonstrate that each object can use a SalesSpeech() method appropriately. Also, use a MakeSale() method two or three times with each object, and display the final contents of each object’s data fields. First, create an abstract class named Salesperson. Fields include first and last names; the Salesperson constructor requires both these values. Include properties for the fields. Include a method that returns a string that holds the Salesperson’s full name—the first and last names separated by a space. Then perform the following tasks: • Create two child classes of Salesperson: RealEstateSalesperson and GirlScout. The RealEstateSalesperson class contains fields for total value sold in dollars and total commission earned (both of which are…Create an Employee class that has properties for the following data: • Employee name • Employee number Next, create a class named ProductionWorker that is derived from the Employee class. The ProductionWorker class should have properties to hold the following data: • Shift number (an integer, such as 1, 2, or 3) • Hourly pay rate The workday is divided into two shifts: day and night. The Shift property will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Create an application that creates an object of the ProductionWorker class and lets the user enter data for each of the object’s properties. Retrieve the object’s properties and display their values.
- (Java) The Sculpture Subclass Write class as follows: The class is named Sculpture, and it inherits from the Painting class. It has a private boolean member variable named humanForm It has a default constructor that assigns the values "No name" to name, "No artist" to artist, -1 to the year, "No medium" to the medium, and false to the humanForm variable. This default constructor calls the five argument constructor. It has a five-argument constructor to assign values to the name, artist, year, medium, and humanForm variables. It has a getter and setter for the humanForm variable. It has a toString() method. This class contains no other methods Make sure to include your name, the name of this class, our course number, and the Activity number in a Javadoc comment at the top. Make sure to write a Javadoc comment for each of these methods.#this is a python program #topic: OOP Design a class called Pokemon using a parameterized constructor so that after executing the following line of code the desired result shown in the output box will be printed. First object along with print has been done for you, you also need to create other objects and print accordingly to get the output correctly. [You are not allowed to change the code below] #Write your code for class here team_pika = Pokemon('pikachu', 'charmander', 90, 60, 10) print('=======Team 1=======') print('Pokemon 1:',team_pika.pokemon1_name, team_pika.pokemon1_power) print('Pokemon 2:',team_pika.pokemon2_name, team_pika.pokemon2_power) pika_combined_power = (team_pika.pokemon1_power + team_pika.pokemon2_power) * team_pika.damage_rate print('Combined Power:', pika_combined_power) #Write your code for subtask 2,3,4 here Output: =======Team 1======= Pokemon 1: pikachu 90 Pokemon 2: charmander 60 Combined Power: 1500 =======Team 2======= Pokemon 1:…Polymorphism Create a class hierarchy that represents different types of employees in a company. Start with a class called Employee that has two methods: calculateSalary() and displayDetails(). Then, create two subclasses of Employee: Manager and Engineer. Override the calculateSalary() method in both subclasses to calculate the salary based on their job role and experience. Override the displayDetails() method in both subclasses to print out a message indicating the details of the employee. Next, create another class called Salesperson that extends Employee and has a method called calculateCommission(). Create two subclasses of Salesperson: SeniorSalesperson and JuniorSalesperson. Override the calculateCommission() method in both subclasses to calculate the commission based on their sales performance. Override the displayDetails() method in both subclasses to print out a message indicating the details of the salesperson. In the main method, create objects of each class and call their…
- 1. The inheritance concept enables certain properties of a superclass to be inherited by its subclasses. Complete the following tasks: (a) Define a class named side_dish that inherits the properties of the Pizza class. (b) Declare a private instance variables named NoItem, price and quantity in side_dish class. (c) Define a public instance method named display () that will display all the data of the side_dish object. Include another default instance method named changeQuantity (int q) that will assign its argument o the side_dish object’s Quantity.

The class should keep the following information infields:• Employee name• Employee number in the format XXX-L, where each X is a digit within the range0-9 and the Lis aletter within the range A-M.• Hire date* Write one or more constructors and the appropriate accessor and mutator methods for theclass.Next, write a class named ProductionWorker that extends the Employee class. TheProductionWorker class should have fields to hold the following information:• Shift (an integer)• Hourly pay rate (a double)The workday is divided into two shifts: day and night. The shift field will be an integer valuerepresenting the shift that the employee works. The day shift is shift 1 and the night shift isshift 2.
