Write an application to test your class?Design a class named Rectangle to represent a rectangle. The class contains:i. Two data fields named width and height.ii. A constructor that creates a rectangle with the specified width and height. iii. A method named getArea() that returns the area of this rectangle.CPEN 60 – OBJECT iv. A method named getPerimeter() that returns the perimeter. 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 35.7. Display the width, height, area, and perimeter of each rectangle in this order. python languageWhat is a static variable? Group of answer choices 1. None of the options are correct. 2. A variable that is common among all instances of the class, and can be accessed without any instantiation of the class. 3. Variables cannot be static, only methods can. 4. A variable whose value remains fixed after creation, and cannot change. 5. A variable that gets destroyed when the instance of the class is no longer used.
- please use visual c# (Date Class) Create a class called Date that includes three pieces of information as auto-implemented properties—a month (type int), a day (type int) and a year (type int). Your class should have a constructor that initializes the three automatic properties and assumes that the values provided are correct. Provide a method DisplayDate that displays the month, day and year separated by forward slashes (/). Write a test app named DateTest that demonstrates class Date’s capabilities.Create a second test class called TicketTest to test that a Ticket object isconstructed correctly when provided reasonable input.a. Write a test method that calls the following constructor with valid arguments:Ticket(Passenger p, Seat s, double price)Before you create the Ticket object:i. Use the wizard to generate the TicketTest classii. Add a test method to the class.iii. In the test method, create a Passenger object. The default constructorof the Passenger class generates a valid name “T. B. A.”, so either ofthe following statements instantiate a Passenger:Passenger passenger = new Passenger();Or:Passenger passenger = new Passenger(new PassengerName(“Mary”, “I”, “Worth”));iv. Create a Seat object.The Seat class has no explicit constructor so you must use the implicitdefault constructor and then call seat.setRow(int i) andseat.setLetter(char c) to specify a specific seat.Unit Testing with JUnitv. Create the ticket object, providing the passenger object, seat object and the price as a…* In your main class: - Define a method called printltemDetails that takes an object of type Item and prints its details in the following format: (Note that each review should be printed on a separate line) Item name: ... Price without tax: ... Price with tax: ... Reviews: - In your main method: 1. Print the sales tax (before creating any object). 2. Create two items. 3. Add three reviews to the two items. 4.
