- Create a class called Fruit that has four instance private variables: • Name : of type string • Country : of type string : The country from which is imported : • Price : of type double • Quantity: of type integer : the available quantity of the fruit. The class should also include the following methods: 1. A constructor with parameters for the different instances variables. 2. A default constructor 3. A set method to update the Price 4. 3 set methods to update respectively the name, country and quantity. 5. Four get methods to get respectively the value of each instance variable Create a program that tests the class Fruit described in the previous question, as follow: 1. Create three objects named Mango, Apple and Orange of type Fruit : Name Mango Apple Orange Country India Italia Tunisia Quantity 100 Price 0.95 0.8 1.1 150 200 2. Display the different instance variables of the Fruit Orange. 3. Update the price of the fruit Mango to the value 1.5 4. Display the total number of Fruits.…1.

Instantiate a Student object and utilize the defined methods***Let the user input those student infodesign a class named Rectangle to represent a rectangle. The class contains: ▪ Two double data fields named width and height that specify the width and height of the rectangle. The default values are 1 for both width and height. ▪ A no-arg constructor that creates a default rectangle. ▪ A constructor that creates a rectangle with the specified width and height. ▪ A method named getArea () that returns the area of this rectangle. ▪ A method named getPerimeter () that returns the perimeter. Draw the UML diagram for the class then implement the class. Write a test program that creates two Rectangle objects-one with width 4 and height 40, and the other with width 3.5 and height 35.9. Display the width, height, area, and perimeter of each rectangle in this order.
- Tests: In the test_sun.py module, create tests for the planet objects. You can (and should) do this before you have written any Planet code at all. Implementation: In the sun.py module (see template), implement a Sun class as described in Section 10.4. Your Sun class should include the following methods: __init__, get_mass, get_radius, get_temperature, and __str__. Your __str__ method should include the following information for each planet: Name, distance from sun, radius, and mass. section 10.4Tests: In the test_sun.py module, create tests for the planet objects. You can (and should) do this before you have written any Sun code at all. Implementation: In the sun.py module (see template), implement a Sun class as described in Section 10.4. Your Sun class should include the following methods: __init__, get_mass, get_radius, get_temperature, and __str__. Your __str__ method should include the following information: Name, radius, mass, and temperature. You can assume that all numerical values are of type float and use type hints in all your method signatures accordingly.In method cook() of the CherryPie class, perform the following tasks: Increment class attribute total_pies. Assign instance attribute num_cherries with the value of parameter cherries_used. Output 'One cherry pie made with ', followed by the value of instance attribute num_cherries, and ' cherries'.

In this question, you are provided a completed superclass – Shape (Do not make any changes to this class!). This class represents generic shapes and has several methods that you will have to override in the Circle and Rectangle subclasses, whose code skeletons are provided as well. You are required to complete these two classes so that they can correctly describe and calculate their attributes. For the Circle class, create the following: A private double instance variable m radius. A constructor that takes two parameters (in the order of color, radius). It should use the parameter for radius to set the m_radius instance variable and then explicitly call the parent class constructor using the super keyword and pass in the color parameter. A method that overrides the calcArea method of the superclass and calculates the area of the circle. The area of a circle can be calculated as 3.14 x r² (where r is the radius). A method that overrides the calcPerimeter method of the superclass and…Create a class Rectangle. The class has attribute length and width, each of which defaults to 1. It has methods that calculate the perimeter and area of the rectangle. It has set and get methods for both length and width. The set method should verify that length and width are each floating-point numbers larger than 0.0 and less than 20.0. Write a program to test class Rectangle
