TOPIC: Inheritance
In Python, modify the given code based on the given specifications below. Create another class, “Food.”
For the Food class, the specifications are:
The object will have the following attributes on initialization:
weight (weight of the food in kg)
energy_add (amount of energy it will add once consumed)
happiness_add (amount of happiness it will add once consumed)
Modify the Child and the Friends classes such that:
Instead of accepting a string (as food) in the eat method, the method should accept a Foodobject
Once a Child/Friendsobject eats a Food object:
The added weight should be the Food object’s weight
The added energy should be the Food object’s energy_add
The added happiness should be the Food object’s happiness_add
The given code (can also be found on the picture):
class Child:
def __init__(self, child_number: int, name: str, weight: float):
self.child_number = child_number
self.name = name
self.weight = weight

- Programming Language = Python 1. Employee and ProductionWorker Classes Write an Employee class that keeps data attributes for the following pieces of information: • Employee name • Employee number Next, write a class named ProductionWorker that is a subclass of the Employee class. The ProductionWorker class should keep data attributes for the following information: • 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 attribute 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. Write the appropriate accessor and mutator methods for each class. Once you have written the classes, write a program that creates an object of the ProductionWorker class and prompts the user to enter data for each of the object’s data attributes. Store the data in the object and then use the object’s accessor methods to retrieve it and display it on the…arrow_forwardParent Class: Food Write a parent class called Food. A food is described by a name, the number of grams of sugar (as a whole number), and the number of grams of sodium (as a whole number). Core Class Components For the Food class, write: the complete class header the instance data variables a constructor that sets the instance data variables based on parameters getters and setters; use validity checking on the parameters where appropriate a toString method that returns a text representation of a Food object that includes all three characteristics of the food Class-Specific Method Write a method that calculates what percent of the daily recommended amount of sugar is contained in a food. The daily recommended amount might change, so the method takes in the daily allowance and then calculates the percentage. For example, let's say a food had 6 grams of sugar. If the daily allowance was 24 grams, the percent would be 0.25. For that same food, if the daily allowance was 36 grams, the…arrow_forwardParking Ticket SimulatorFor this assignment you will design a set of classes that work together to simulate apolice officer issuing a parking ticket.

- People in School Objective: At the end of the activity, the students should be able to: Create a program that exhibits inheritance. Procedure: Write a simple information system that will store and display the complete information of a student, faculty, or employee. Create four (4) no-modifier classes named Person, Student, Faculty, and Employee. Create a public class named CollegeList. This class shall contain the main method. Refer to the UML Class Diagram for the names of the variables and methods. The (-) symbol represents private variables, while (+) represents public method. This should be the sequence of the program upon execution: Prompt the user to select among Employee, Faculty, or Student, by pressing E, F, or S. Ask the user to type the name and contact For Employee, ask the user to type the employee's monthly salary and the department where he/she belongs to (Ex. Registrar). Then, display name, contact number, salary, and For Faculty, ask the user to press Y if…arrow_forwardUse JAVA - This task helps you understand how constructors work in inheritance Create a superclass, called SuperClass.
