1. Object
2. SuperClass
3. Parent
4. System
Step by step
Solved in 2 steps
- The NET Framework has a class called that includes a number of methods for conducting sophisticated mathematical calculations.Using Python, create a class called cellphone. The cellphone class has the following fields: color, manufacturer model. instantiate the cellphone class 5 times. modify the properties. display all the properties.Choose necessary patters, draw the UML and code just company class methods on paper. A car company makes a car produce application. There are diffrerent types of models that the company builds as sedan and sport. Each model has some shared and distinguishing features. The object creation process should conduct by a central class. The second central class should not be created in the application.
- C++ Design a class named Rectangle to represent a rectangle. The class contains: Two double data fields named width and height that specify the width and height of the rectangle. A no-arg constructor that creates a rectangle with width 1 and height 1 . A constructor that creates a rectangle with the specified width and height. The accessor and mutator functions for all the data fields. A function named getArea() that returns the area of this rectangle. A function named getPerimeter() that returns the perimeter. Implement the class. Write a test program that creates two Rectangle objects. Assign width 4 and height 40 to the first object and width 3.5 and height 35.9 to the second. Display the width, height, area, and perimeters of the first object and then the second object.What is the difference between a class and an object?I need help with this PLEASE NO JAVA NO C++ ONLY PYTHON PLZ Create a class object with the following attributes and actions: Class Name Class number Classroom Semester Level Subject Actions: Store a class list Print the class list as follows: Class name Class Number Semester Level Subject Test your object: Ask the user for all the information and to enter at least 3 classes test using all the actions of the object print using the to string action Describe the numbers and text you print. Do not just print numbers or strings to the screen explain what each number represents.
- When programs becomes larger and more complex, you often divide the necessary processing into classes. Mention three (3) benefits of using Classes in Visual Basic.Java program: 1. Create a class named Rectangle that has instance variables height and width. Provide a constructor that initializes the instance variables based on parameter values, getter and setter methods for the instance variables, a toString method, and a method named computeSurfaceArea(), that returns the surface area of the rectangle. 2. Create a child class named RectPrism that contains an additional instance variable named depth. Provide a constructor, getter and setter methods for the new instance variable, and a method named computeVolume(), that returns the volume of the rectangular prism. Override the toString() and the computeSurfaceArea() methods. 3. Write an application called Demo, that instantiates a rectangle and a rectangular prism, and tests all the methods. Make sure you indent and comment your code based on the examples in the textbook. Don’t forget to include your name, the course number, title of the assignment, and today’s date.Create a class called cellphone. The cellphone class has the following fields: color, manufacturer model. instantiate the cellphone class 5 times. modify the properties. display all the properties.
- Design a class named Author with the following members: A field for the author’s name (a String) A field for the author’s year of birth (an int) One or more constructors and appropriate accessor and mutator methods A toString method that displays the author’s info as: Author: Mary Shelley (1797) Save the file as Author.java. Next, create an abstract class named Book with the following members: A field for the book title (a String) A field for the book author (a reference to an Author object) A field for the book price (a double) A constructor that requires the title and author Get methods for the title, author, and price An abstract method named setPrice A toString method that displays the book’s title, author’s info, and price as: Frankenstein Author: Mary Shelley (1797) Price: $23.95 Save the file as Book.java. Create Fiction and NonFiction child classes of Book. Each must include a setPrice method that sets the price for all Fiction books to $23.95 and for all NonFiction books…In this Assignment we will build a simple graphical application that is responsive and that uses basic widgets and demonstrates event handling. The screen shot below shows the expected result In this Assignment we will build a simple graphical application that is responsive and that uses basic widgets and demonstrates event handling. The screen shot below shows the expected result You must not use any other library except tkinter. Your code must run on a standard machine. Your code must be written as a class that inherits from Tk and the application must resize gracefully. The apps must start in a usable state i.e. all the relevant values of the input widget must be set. So if you click ok when the app starts, then you should get the pop-up message shown in the last page. The reset button must set the app to the initial start state. Widget must align vertically as well as horizontally with their matching widget Application not designed as a class. Application not responsive: The…Java Object Oriented Programming Create a Shape class that shall have color and filled instance variables of enum Color and boolean type. The filled boolean variable shall show, whether the shape is filled (colored). The enum Color shall be defined within the class having 4 color names (choose any four). Also define getArea and getPerimeter method in Shape class, both shall return 0. Create Rectangle class with length and width attributes and a Circle class with radius attribute, of type double. Properly encapsulate all fields. Circle and Rectangle shall extend Shape class and override getArea and getPerimters methods as per its type and specific formula. In Test class, create an object of Rectangle and Circle, by initializing all attributes in constructor and print both shapes' area and perimters. In Test class, define a static method with following signature, public static void printEachShapeCount(Shape... shapes) As you know, the parent type variable can hold the…
