PYTHON:
I am working on a problem using inheritance (OOP). The first question, Create a class named Circle that will inherit properties and methods from a class named Ellipse, and you do not want to add any other properties or methods to the class, my answer was:
class Circle(Ellipse):
pass
For the next problem, I need to write a workable code defining the class Ellipse with a reasonable number of properties and methods. Mostly it is a practice to understand how inheritance works. I am having trouble figuring out where to go from here so I have a program to print my answers out. This is what I have so far. Any help would be appreciated.
import math
class Ellipse:
def _init_(self, length, width):
self.length = length
self.width = width
def area(self):
return 3.14 * self.length * self.width
def perimeter(self):
return 3.14 * (self.length * self.width)
class Circle(Ellipse):
def _init_(self, radius):
super()._init_(radius, radius)

You have been asked to design a number of classes to represent the various taxi fares (trips with passengers) and their various fee structures, by using inheritance in Python. a computeCharges method that returns the total charges for the cab fare, using the instance variables and the defined constants (i.e., kms multiplied by the cost per km, plus minutes multiplied by the cost per minute) Please read all parts of this question below before starting the question. Include the completed code for all parts of this question in a file called taxi_company.py- NOTE: To implement encapsulation, all of the instance variables/fields should be considered private.

North Carolina. You will be working in a large development team in the process of building the firm's first online reservation system. your first assignment is to build the components that will check the age of the customer and then assign them a car. you will be building the business logic classes, so you do not have to worry about the forms of communicating with the user or data access classes to communicate with the database. To test your classes, you will use them in a test application. The requirements for your classes and the testing application are as follows: -You will design and build 2 components of the online reservation system(ORS). There will be one class to represent customers and another to represent vehicles. -Each class should have at least 2 members and 2 methods -The ORS will need to be able to check to make sure the customer in question is at least 25 years old.

- {In Java Programming Please} 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.

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.
