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:

- In previous chapters, you have created programs for the Greenville Idol competition. Now create a Contestant class with the following characteristics: The Contestant class contains public static arrays that hold talent codes and descriptions. Recall that the talent categories are Singing Dancing, Musical instrument, and Other. The class contains an auto-implemented property that holds a contestants name. The class contains fields for a talent code and description. The set accessor for the code assigns a code only if it is valid. Otherwise, it assigns I for Invalid. The talent description is a read-only property that is assigned a value when the code is set. Modify the GreenvilleRevenue program so that it uses the Contestant class and performs the following tasks: The program prompts the user for the number of contestants in this years competition; the number must be between 0 and 30. The program continues to prompt the user until a valid value is entered. The expected revenue is calculated and displayed. The revenue is $25 per contestant. The program prompts the user for names and talent codes for each contestant entered. Along with the prompt for a talent code, display a list of the valid categories. After data entry is complete, the program displays the valid talent categories and then continuously prompts the user for talent codes and displays the names of all contestants in the category. Appropriate messages are displayed if the entered code is not a character or a valid code.Class Student __init__(self, id: int, fist_name: str, last_name: str, town:str): """ This creates a student object with the specified ID first and last name and home town. This constructor should also create data structure for holding the students grades for all of there assignments. Additionally it should create a variable that holds the student's energy level which will be a number between 0 and 1. :param id: The student's identifiaction number :param fist_name: The student's first name :param last_name: The student's last name :param town: The student's home town """ get_id(self)->int: """ Returns the ID of the student as specified in the constructor. :return: The student's ID """ get_first_name(self) -> str: """ Returns the first name of the student. :return: The student's first name """ set_first_name(self, name:str): """ Changes the student first name to the specified value of the name parameter. :param name: The value that the first name of the student will equal. """…In Python: Write a class named Pet, which should have the following data attributes: _ _name (for the name of a pet) _ _animal_type (for the type of animal that a pet is. Example values are 'Dog','Cat', and 'Bird') _ _age (for the pets age) The Pet class should have an _ _init_ _ method that creates these attributes. It should also have the following methods: set_nameThis method assigns a value to the _ _name field set_animal_typeThis method assigns a value to the _ _animal_type field set_ageThis method assignsa value to the _ _age field get_nameThis method assignsa value to the _ _name field get_animal_typeThis method assignsa value to the _ _animal_type field get_ageThis method assignsa value to the _ _age field Once you have written the class, write a program that creates an object of the class and prompts the user to enter the name, type and age of his or her pet. This data should be stored as the objects attributes. Use the objects accessor methods to retrieve the pets…
- Create a BowlingTeam class The class has 2 fields: a field for the team name and an array that holds the team members’ names. Create get and set methods for the teamName field. Add a setMember method that sets a team member’s name. The method requires a position and a name, and it uses the position as a subscript to the members array. Add a getMember method that returns a team member’s name. The method requires a value used as a subscript that determines which member’s name to return. Create a BowlingTeamDemo class. In the main method include the following: Declare 2 variables: name and a constant NUM_TEAMS that holds 4 Bowling Team objects. Declare and instantiate an array teams of BowlingTeam objects. Using nested for loops, prompt the user to enter the 4 team names and enter the team members’ names. Using another nested for loop, output each team’s name and their team members’. Output should look like: Members of team The Lucky Strikes Carlos Diego Rose Lynn Members of team I…Rectangle Object Monitoring Create a Rectangle class that can compute the total area of all the created rectangle objects using static fields (variables). Remember that a Rectangle has two attributes: Length and Width. Implement the class by creating a computer program that will ask the user about three rectangle dimensions. The program should be able to display the total area of the three rectangle objects. For this exercise, you are required to apply all OOP concepts that you learned in class. Sample output: Enter Length R1: 1 Enter Width R1: 1 Enter Length R2: 2 Enter Width R2: 2 Enter Length R3: 3 Enter Width R3: 3 The total area of the rectangles is 14.00 Note: All characters in boldface are user inputs.2. The MyInteger Class Problem Description: Design a class named MyInteger. The class contains: n [] [] A private int data field named value that stores the int value represented by this object. A constructor that creates a MyInteger object for the specified int value. A get method that returns the int value. Methods isEven () and isOdd () that return true if the value is even or odd respectively. Static methods isEven (int) and isOdd (int) that return true if the specified value is even or odd respectively. Static methods isEven (MyInteger) and isOdd (MyInteger) that return true if the specified value is even or odd respectively. Methods equals (int) and equals (MyInteger) that return true if the value in the object is equal to the specified value. Implement the class. Write a client program that tests all methods in the class.
- A. Car Class Create a Python Program where you write a class named Car that has the following data attributes: • _ _year_model (for the car's year model) • __make (for the make of the car) • _ _speed (for the car's current speed) The Car class should have an _init_ method that accepts the car's year model and make as arguments. These values should be assigned to the object's _year_model and make data attributes. It should also assign 0 to the __speed data attribute. The class should also have the following methods: accelerate() The accelerate method should add 5 to the speed data attribute each time it is called. brake() The brake method should subtract 5 from the speed data attribute each time it is called. • get_speed() The get_speed method should return the current speed. Next, design a program that creates a Car object then calls the accelerate method five times. After each call to the accelerate method, get the current speed of the car and display it. Then call the brake method…Introduction In this project, you will complete a C++ class by writing a copy constructor, destructor, and assignment operator. Furthermore, you will write a tester class and a test program and use Valgrind to check that your program is free of memory leaks. Finally, you will submit your project files on GL. If you have submitted programs on GL using shared directories (instead of the submit command), then the submission steps should be familiar. In this project we develop an application which holds the information about a digital art piece. There are two classes in this project. • The Random class generates data. The implementation of this class is provided. It generates random int numbers for colors. To create an object of this class we need to specify min and max values for the constructor. The colors fall between 30 and 37 inclusively. The Art class generates random colors and stores the color values. You implement the Art class. An object of the Art class is a digital masterpiece.…design a Club class and use it to create an application that simulates asoccer league tournament.
