1. A polynomial can be represented as a linked list, where each node called a polyNode contains the coefficient and the exponent of a term of the polynomial. For example, the polynomial 4x³ + 3x²-5 would be represented as the linked list: 43 I 3 L -50 - 5xo 2 7. 4x3 3x² Write a Polynomial class that has methods for creating a polynomial, reading and writing a polynomial, and adding a pair of polymomials. In order to add 2 polynomials, traverse both lists. If a particular exponent value is present in either one, it should also be present in the resulting polynomial unless its coefficient is zero.

- PYTHON PROGRAMMING 1.Create an empty class called Car. 2.Create a method called initialize in the class, which takes a name as input and saves it as a data attribute. 3.Create an instance of the class, and save it in a variable called car. 4.Call the initialize method with the string “Ford".Creates a class StudentPhD extending the class Student with two more attributes: specialty and supervisorName; a. Add a constructor to create a StudentPhd b. Add a display method: display need to override (polymorphism) the previous display method of Student class;Task 5 Create an Employee Class that will have Two instance variable: name and workingPeriod A class method named employeeByJoiningYear(): • To create an Employee object by joining year for calculating the working period o it will have two Parameter name and year • A static method experienceCheck() to check if an Employee is experienced or not o It will take working period and gender as parameter o If an employee's working period is less than 3, he or she is not experienced [You are not allowed to change the code below] # Write your code here employee1 = Employee('Dororo', 3) employee2 = Employee.employeeByJoiningYear('Harry', 2016) 5 print(employee1.workingPeriod) print(employee2.workingPeriod) print(employee1.name) Оutput 3 Dororo Harry He is not experienced She is experienced print(employee2.name) print(Employee.experienceCheck(2, "male")) print(Employee.experienceCheck(3, "female"))
- Purpose To review interfaces Directions Your task for this lab is to implement and test a class to store ratings of items. Your Rating class should have the following fields and methods: private double sumOfRatings - the sum of all of the ratings private int raters - the number of people who have rated an item public Rating () initialize both fields to zero public Rating (double sumofRatings, int raters) - initialize the fields to the parameter values public void addRating (double newRating) - increase the sumOfRatings by newRating and increase the number of raters by one public double getAverageRating () return the average rating; if there are no raters so far, return 0.0 public String toString() - display the average rating and how many reviews it is based on; for example, if the sum of the ratings is 32 and that is based on ratings from ten people, the toString method will return "3.2 based on 10 reviews"Create the following class diagram: The print method in: - Author prints the Authors data - Page prints page no and text - Textbook prints the subject and all pages - Novel prints the genre and all pages The toString method in: - Book returns title and authors - textbook returns subject in additions to super toString - Novel genre in additions to super toString Test your implementation create objects of different types example : - Create a book of type Novel which has many pages and several authors - Create a book of type Textbook which has many pages and several authors - Access these objects polymorphically, variable of class book contains objects of its subclasses Textbook and novel - Print a hall book - Print a single page of a book - Print the book and its authorsDesign a class named StopWatch. The class contains:■ The private data fields startTime and endTime with get methods.■ A constructor that initializes startTime with the current time.■ A method named start() that resets the startTime to the current time.■ A method named stop() that sets the endTime to the current time.■ A method named getElapsedTime() that returns the elapsed time for thestop watch in milliseconds.Draw the UML diagram for the class, and then implement the class. Write a test program that measures the execution time of adding numbers from 1 to 1,000,000.
