3. Write a new class named "IntVariable" that must inherit from the "BoolVariable" class. This class manages a variable name (string) and a value (integer). Please note that this class must make use of inheritance. The class must at least provide the following methods: o toString() method that can return a string in the following format: variable-name(variable-integer-value) such as count(100) o isGreater() method that accepts another IntVariable object and returns true if its own integer value is greater than the integer value of the given object and false otherwise. Its constructor will generate exception with the right error information

All vehicles used for transportation in the U.S. must have identification, which varies according to the type of vehicle. For example, all automobiles have a unique Vehicle Identification Number (VIN) assigned by the manufacturer, plus a license plate number assigend by the state in which the auto is registerd. Your task is to modify the Auto class below to override the equals method of the Vehicle class to test that the VIN and license plate number are identical.

Implement the Seller class as a derived class of Person class. Create the seller.h and seller.cppfiles for this class. The Seller class contains additional data members that hold a seller’s:o average star rating received from the buyers, ando total number of items sold.These data should be accessible by its derived classes. (should these data be private, public, orprotected?) The following methods are included in the seller class:• A default constructor and a copy constructor• A constructor that receives all of the data for a seller.(for the constructors, make sure to call the base class constructor as appropriate)• Appropriate get and set functions for the new data in this class• print() – overrides the base class print() to print the base class data and print all additionalseller data with appropriate messages. Make sure to call the base class print to print thebase class data.• read() – overrides the base class read() to read the base class data and reads all additionalseller data…
This program extends the earlier "Online shopping cart" program. (Consider first saving your earlier program). (1) Extend the ItemToPurchase class to contain a new attribute. item_description (string) - Set to "none" in default constructorImplement the following method for the ItemToPurchase class. print_item_description() - Prints item_description attribute for an ItemToPurchase object. Has an ItemToPurchase parameter. Ex. of print_item_description() output: Bottled Water: Deer Park, 12 oz. (2) Build the ShoppingCart class with the following data attributes and related methods. Note: Some can be method stubs (empty methods) initially, to be completed in later steps. Parameterized constructor which takes the customer name and date as parameters Attributescustomer_name (string) - Initialized in default constructor to "none"current_date (string) - Initialized in default constructor to "January 1, 2016"cart_items (list)Methodsadd_item()Adds an item to cart_items list.

Add a private method simplify() to your Fraction class that converts a fraction to its simplest form. For example, the fraction 20 / 60 should be stored in the class instance variables as 1 / 3 (i.e. numerator = 1, denominator = 3). N.B.you will need a method to determine the Greatest Common Divisor (GCD.both of these methods (simplify and gcd) must be private. Asthese methods are private, client programs cannot access them. They can only be accessed within the Fraction class. Given their purpose, it would mean that any Fraction class method that modifies theinstance variables (e.g.: input, add, constructor, set) should call the simplify() method to reduce the instance variables to their minimum values. import java.util.ArrayList;import java.util.Scanner; class Fraction{private int n, d;public Fraction(){this.n = this.d = 0;}public Fraction(int n, int d){this.n = n;this.d = d;} public int getNum(){return n;}public int getDen(){return d;}public boolean isZero(){return(getNum() == 0…

In this exercise, you have to calculate the student's total marks using the concept of Classes Problem Statement# Write a Java class called Student with ● private fields: ○ name(String type) ○ mark1 and mark2 (double type) And methods: ● getMarks(int markNumber), a method which should return mark1 if markNumber equals 1 and mark2 otherwise. ● calcTotal() method should take the two marks entered and return their sum. Also define two constructors: ● A default constructor that takes no parameters and initializes the values to zeros and null. ● A constructor that takes the three variables and sets them as the values of the appropriate fields. Input# Name of the student and the marks obtained in the first and second tests Output# Sum of both marks Sample Input# Student student = new Student("Jack", 60, 70); Sample Output# getMarks(1) => 60 getMarks(2) => 70 calcTotal() => 130.0 Part of solution class Student { // Define private fields here public Student() { // Write…
++1.+Write a class about a book which has following properties: • isbn • price • titleIn a Test class we are supposed to create objects as below: Book b1= new Book(); Book b2= new Book(544444, “Java”); Book b3= new Book(54444444, C++, 5.6); Book b4= new Book (“Python, 7.9, 8888899988); and we are supposed to print objects with the following statement: 5.

In this java assignment, we will be creating a pay stub for an employee using classes. Each class must be implemented into their own file, a total of 5 classes/files. We are going to implement the following classes: Employee – This class represents an employee. It needs the following fields exposed via getters and setters: Employee ID (we will need to make this unique, for now, just hard code it to 1). First name, Last name, Middle initial Address, City, Zip Phone, Email Hourly Rate PayPeriod – This class represents an employee’s payment information. An employee will eventually have more than one pay period. It must contain the following fields (exposed via getters and setters): Pay period Id (hard code it for now) Employee Id (who is this for) Start Date, End Date Number of hours PayrollManager – This class provides the functionality we need to compute and display our payroll. It should implement the following methods: double CalculateGrossPay (Employee, Payperiod) – This…

In Python: Using class Point that you implemented in assignment 9, implement a class called ThreeDPoint that inherits class Point. The class has (other than the inherited x, and y) another integer named z. Class ThreeDPoint has the following: Default initializer, used to create objects of type ThreeDPoint, by default x, y, and z are set to 1. initializer with three parameters for x, y, and z. set and get methods for z. Override Method __str__, which returns a string that represent the ThreeDPoint (e.g., p = [4,5, 6]).
