Tests: In the test_sun.py module, create tests for the planet objects. You can (and should) do this before you have written any Planet code at all. Implementation: In the sun.py module (see template), implement a Sun class as described in Section 10.4. Your Sun class should include the following methods: __init__, get_mass, get_radius, get_temperature, and __str__. Your __str__ method should include the following information for each planet: Name, distance from sun, radius, and mass.

IN C++ Lab #6: Shapes Create a class named Point. private attributes x and y of integer type. Create a class named Shape. private attributes: Point points[6] int howManyPoints; Create a Main Menu: Add a Triangle shape Add a Rectangle shape Add a Pentagon shape Add a Hexagon shape Exit All class functions should be well defined in the scope of this lab. Use operator overloading for the array in Shape class. Once you ask the points of any shape it will display in the terminal the points added.
(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#
Class: Square Create a class called "Square", which is inherited from“TwoDimensionShape” class. The "Square" class is used to calculate theArea and the Perimeter of square shapes when their side-length is given, or in contrast,finding the side-length of the square when the Area or the Perimeter of the square is given.The specifications of this class are below. Data Members (Attributes): All are private. sideLength: the sidelight (L) of the square. Methods/Operations/Getters/Setters: Default Constructor: when creating an object this constructor must set the side-length of the square by calling the method setSideLength(). Also, this constructor willcall the findArea() and the findPerimeter() in addition to summaryPrint() to calculateand print all needed information. User-Defined Constructor: when creating an object this constructor shouldfind the side-length of the square by calling the method findSquareSideLength()and pass the Area or the…
Computer Science You are required to develop a small chatting application where two or more friends can communicate each other through messages. Create a class Message which has Date d, and message (string). Provide getters/setters, constructors, toString. Create a class Friend having String name, String contact, email and ArrayList of Messages provide getters/setters, constructors, toString addMessage(Message m) method which will add new message to the list. Provide following options to the user using JFrame. Login which will help user login to the application. View Friends (Display List of All Friends) View Messages ( This should display all message of a Friend) Send message (This should ask for friend name and message match the friend name and write that message to the array list).
Define a class called Book. The Book class should store attributes such as the title, ISBN, author, edition, publisher, and year of publication. These attributes must be private. Provide public get/set methods in this class to access these attributes. Test your Book class by creating several books and displaying the attributes. Define a class called Bookshelf, which contains only a main() method. The Bookshelf class must create a dozen (12) Book objects with distinct attributes, and it must store them in an ArrayList of Books. The Bookshelf class must then list all the attributes of all books in the ArrayList in the order they were entered into the ArrayList. Create a sort function for Bookshelf, which will sort books in the ArrayList in ascending order by name, and then by year of publication.
Design a class called Post. This class models a StackOverflow post. It should have properties for title, description and the date/time it was created. We should be able to up-vote or down-vote a post. We should also be able to see the current vote value. In the main method, create a post, up-vote and down-vote it a few times and then display the the current vote value.
Book Donation App Create a book-app directory. The app can be used to manage book donations and track donors and books. The catalog is implemented using the following classes: 1. The app should have donors-repo.js to maintain the list of donors and allow adding, updating, and deleting donors. The donor object has donorID, firstName, lastName, and email properties. This module should implement the following functions: • getDonor(donorId): returns a donor by id. • addDonor(donor): adds a donor to the list of donors; donorID should be autoassigned a random number. • updateDonor(donor): updates the donor having the matching donorID. • deleteDonor(donorID): delete the donor with donorID from the list of donors, only if they are not associated with any books. 2. The app should have books-repo.js to maintain the list of donated books and allow adding, updating, and deleting books. The book object has bookID, title, authors, and donorID properties. • donorID references the book’s donor. This…
Class Student This class represents a single student __init__(self, id: int, fist_name: str, last_name: str, town:str): """ This creates a student object with the specified ID first and last name and home town. This constructor should also create data structure for holding the students grades for all of there assignments. Additionally it should create a variable that holds the student's energy level which will be a number between 0 and 1. The student start out with 1 (100%) energy. :param id: The student's identifiaction number :param fist_name: The student's first name :param last_name: The student's last name :param town: The student's home town """ get_id(self)->int: """ Returns the ID of the student as specified in the constructor. :return: The student's ID """ get_first_name(self) -> str: """ Returns the first name of the student. :return: The student's first name """ set_first_name(self, name:str):…
JAVA 2 LANGUAGE 8.2 (The Stock class) Following the example of the Circle class in Section 8.2, design a class named Stock that contains: ■ A string data field named symbol for the stock’s symbol. ■ A string data field named name for the stock’s name. ■ A double data field named previousClosingPrice that stores the stock price for the previous day. ■ A double data field named currentPrice that stores the stock price for the current time. ■ A constructor that creates a stock with the specified symbol, name, previousClosingPrice, and currentPrice. ■ A method named getChangePercent() that returns the percentage changed from previousClosingPrice to currentPrice. The formula to be used is (currentPrice - previousClosingPrice) / previousClosingPrice. Draw the UML diagram for the class and then implement the class (write the code for the class). Write a test program (application) in which you create a Stock object stock1 with the stock symbol ORCL, the name Oracle Corporation, the…
Inheritance, Polymorphism, ArrayLists, Throwing Exceptions The UML diagram below shows a set of classes designed to represent a music collection from 1995. The constructors and methods all function in the standard way, except: The equipmentRequired method should return “Record Player” or “CD Player” as appropriate.The getAlbum method of the NinetiesMusicCollection class accepts an index and returns the corresponding Album object. This method throws an IllegalArgumentException if the index is out of range. (This is the only exception you have to throw anywhere in your code.)In the NinetiesMusicCollection constructor, you can assume the ArrayList<Album> object passed as an argument is not null . Don’t worry about privacy leaks.Implement this set of classes in Java. Note the italics on the Class name “Album” and the method name “equipmentRequired” in the Album class.
Design a new Account class as follows:■■ Add a new data field name of the String type to store the name of thecustomer.■■ Add a new constructor that constructs an account with the specified name, id,and balance.■■ Add a new data field named transactions whose type is ArrayList thatstores the transaction for the accounts. Each transaction is an instance of theTransaction class, which is defined as shown in Figure ■■ Modify the withdraw and deposit methods to add a transaction to thetransactions array list. Write a test program that creates an Account with annual interest rate 1.5%,balance 1000, id 1122, and name George. Deposit $30, $40, and $50 to theaccount and withdraw $5, $4, and $2 from the account. Print an account summarythat shows the account holder name, interest rate, balance, and all transactions.
