(Enhancing Class Rectangle) Create a more sophisticated Rectangle class than the one you created in Exercise 17.11. This class stores only the Cartesian coordinates of the four corners of the rectangle. The constructor calls a set function that accepts four sets of coordinates and verifies that each of these is in the first quadrant with no single x- or y-coordinate larger than 20.0. The set function also verifies that the supplied coordinates do, in fact, specify a rectangle. Provide member functions that calculate the length, width, perimeter and area. The length is the larger of the two dimensions. Include a predicate function square that determines whether the rectangle is a square.

- (Data exploration and Mining Method Proposal): Here you will explore your data both visually and/or statistically then propose methods for mining it. I- Present a simple statistical exploration of your data (correlations, standard deviations, means, medians). Also explore your data visually using methods such as histograms, scatterplots ,heat maps, box and whisker plots...) II- Propose a data mining method covered in the class to apply on your data.arrow_forward(Geometry: MyRectangle2D class) Define the MyRectangle2D class that contains: Two double data fields named x and y that specify the center of the rectangle with getter and setter methods. (Assume the rectangle sides are parallel to the x- or y-axis.) The data fields width and height with getter and setter methods. A no-arg constructor that creates a default rectangle with (0, 0) for (x, y) and 1 for both width and height. A Constructor that creates a rectangle with the specified x, y, width, and height. A method getArea() that returns the area of the rectangle. A method getPerimeter() that returns the perimeter of the rectangle. A method contains(double x, double y) that returns true if the specified point (x, y) is inside this rectangle (see Figure 10.24a ). A method contains(MyRectangle2D r) that returns true if the specified rectangle is inside this rectangle (see Figure 10.24b ). A method overlaps(MyRectangle2D r) that returns true if the specified rectangle overlaps with this…arrow_forward(Triangle class) Design a new Triangle class that extends the abstract GeometricObject class. Draw the UML diagram for the classes Triangle and GeometricObject and then implement the Triangle class. Write a test program that prompts the user to enter three sides of the triangle, a colour, and a Boolean value to indicate whether the triangle is filled. The program should create a Triangle object with these sides and set the colour and filled properties using the input. The program should display the area, perimeter, colour, and true or false to indicate whether it is filled or not.arrow_forward
- (Tic-Tac-Toe) Write a program that allows two players to play the tic-tac-toe game. Your program must contain the class ticTacToe to implement a ticTacToe object. Include a 3-by-3 two-dimensional array, as a private member variable, to create the board. If needed, include additional member variables. Some of the operations on a ticTacToe object are printing the current board, getting a move, checking if a move is valid, and determining the winner after each move. Add additional operations as needed.arrow_forward(Rectangle Class) Create a class Rectangle with attributes length and width, each of whichdefaults to 1. Provide member functions that calculate the perimeter and the area of the rectangle.Also, provide set and get functions for the length and width attributes. The set functions should verify that length and width are each floating-point numbers larger than 0.0 and less than 20.0.arrow_forward(Use BigInteger for the Rational class) Redesign and implement the Ratio-nal class in Listing 13.13 using BigInteger for the numerator and denomina-tor. Write a test program that prompts the user to enter two rational numbers and display the results as shown in the following sample run: Enter the first rational number: 3 454Enter the second rational number: 7 2389 3/454 + 7/2389 = 10345/10846063/454 – 7/2389 = 3989/10846063/454 * 7/2389 = 21/10846063/454 / 7/2389 = 7167/31787/2389 is 0.0029300962745918793arrow_forward
- (Rectangle Class) Create class Rectangle. The class has attributes length and width, each of which defaults to 1. It has read-only properties that calculate the Perimeter and the Area of the rectangle. It has properties for both length and width. The set accessors should verify that length and width are each floating-point numbers greater than 0.0 and less than 20.0. Write an app to test class Rectangle. THIS IS C#arrow_forward(Account class)Create an Account class that a bank might use to represent customers’ bank accounts. Include a data member of type int to represent the account balance. Provide a constructor that receives an initial balance and uses it to initialize the data member. The constructor should validate the initial balance to ensure that it’s greater than or equal to 0. If not, set the balance to 0 and display an error message indicating that the initial balance was invalid. Provide three member functions. Member function credit should add an amount to the current balance. Member function debit should withdraw money from the Account and ensure that the debit amount does not exceed the Account’s balance. If it does, the balance should be left unchanged, and the function should print a message indicating "Debit amount exceeded account balance." Member function get_Balance should return the current balance. Create a program that creates two Account objects and tests the member functions of class…arrow_forward(Combining Class Time and Class Date) Combine the modified Time class of Exercise 17.7and the modified Date class of Exercise 17.8 into one class called DateAndTime. (In Chapter 19, we’lldiscuss inheritance, which will enable us to accomplish this task quickly without modifying the existing class definitions.) Modify the tick function to call the nextDay function if the time increments into the next day. Modify functions printStandard and printUniversal to output the dateand time. Write a program to test the new class DateAndTime. Specifically, test incrementing thetime into the next day.arrow_forward
- (Querying an Array of Invoice Objects) Use the class Invoice provided in the lab assignment to create an array of Invoice objects.Class Invoice includes four properties—a PartNumber (type int), a PartDescription (type string), a Quantity of the item being purchased (type int) and a Price (type decimal).Write a console application that performs the following queries on the array of Invoice objects and displays the results:a) Use LINQ to sort the Invoice objects by PartDescription.b) Use LINQ to sort the Invoice objects by Price.c) Use LINQ to select the PartDescription and Quantity and sort the results by Quantity.d) Use LINQ to select from each Invoice the PartDescription and the value of the Invoice(i.e., Quantity * Price). Name the calculated column InvoiceTotal. Order the results by Invoice value. [Hint: Use let to store the result of Quantity * Price in a new range variable total.]e) Using the results of the LINQ query in Part d, select the InvoiceTotals in the range$200 to…arrow_forward(RationalNumber Class) Create a class RationalNumber (fractions) with these capabilities:a) Create a constructor that prevents a 0 denominator in a fraction, reduces or simplifiesfractions that are not in reduced form and avoids negative denominators.b) Overload the addition, subtraction, multiplication and division operators for this class.c) Overload the relational and equality operators for this classarrow_forward(In python please) Q#4 Write a class named Patient that has attrib already have the code written I just need to know how to total the bill portion.utes for the following data: First name and last name Date of birth Address, city, state, and ZIP code Phone number The Patient class’s _ _init_ _ method should accept an argument for each attribute.Next, write a class named Appointment that represents an appointment that is assigned to a patient.The Procedure class should have attributes for the following data: Date of the appointment Reason of the appointment Name of the practitioner who visited a patient Bill for the appointment The Appointment class’s _ _init_ _ method should accept an argument for each attribute. Next, write a program that creates an instance of the Patient class, initialized with sample data.
