Magic Squares One interesting application of two-dimensional arrays is magic squares. A magic square is a square matrix in which the sum of every row, every column, and both diagonals is the same. Magic squares have been studied for many years, and there are some particularly famous magic squares. In this exercise you will write code to determine whether a square is magic. File Square.java contains the shell for a class that represents a square matrix. It contains headers for a constructor that gives the size of the square and methods to read values into the square, print the square, find the sum of a given row, find the sum of a given column, find the sum of the main (or other) diagonal, and determine whether the square is magic. The read method is given for you; you will need to write the others. Note that the read method takes a Scanner object as a parameter. File SquareTest.java contains the shell for a program that reads input for squares from a file named magicData and tells…

You are given a Restaurant class below, which represents restaurant information scraped from online reviews website. public class Restaurant { private String name; //name of the restaurant private String address; //restaurant's address private int rating; //average rating of all reviews (1-5) ... // constructors, getters, setters, toString() are already defined Assume 100 Restaurant objects are stored inside the array. Using the array: Calculate and print the average rating of all restaurants.

Write an application (including algorithm) that uses a class called “Book” (seedetails below). The application must perform the following tasks. Create an array of “Book” objects (i.e., array must be able to store 2books). Create 2 “Book” objects initialized as follows.o title = “C++ Textbook”; Author = “Pete Parker”; Publisher =“Cengage”, ISBN = “0123456789”; subject = “Computer Programming”;o title = “Java Textbook”; Author = “Bruce Wayne”; Publisher = “McGrawHill”, ISBN = “9876543210”; subject = “Computer Programming”; Add the two books to the array.o Assume the two publishers have merged into a new company called“BookConglomerate”. Use a loop to create statements to modify thepublisher field with the new publisher name. Display the following information for both bookso Book Title (i.e., “C++ Textbook” or “Java Textbook”)o Authoro Publishero ISBNo SubjectThe Book class must contain the following. Constructor with parameters that initialize all instance variables title, author,…
IN C# PLEASE Create class Cube. The class has attributes length and width and depth, each of which defaults to 1. It has read-only properties that calculate the Perimeter and the Area for a side of the cube, and another that calculates the cubed feet for the cube. (You will have to research how to do that calculation online) It has properties for length and width and depth. The set accessors should verify that length and width and depth are all floating-point numbers greater than 0.0 and less than 20.0. Write an app to test class Cube by creating 3 cubes of different sizes.
Please answer this with PYTHON LANGUAGE. thank you The developers of a free online game named Sugar Smash have asked you to develop a class named SugarSmashPlayer that holds data about a single player. The class contains the following fields: idNumber - the player’s ID number (of type int), name - the player's screen name (of type String), scores - an array of integers that stores the highest score achieved in each of 10 game levels Include get and set methods for each field. The get method for scores should require the game level to retrieve the score for. The set method for scores should require two parameters—one that represents the score achieved and one that represents the game level to be retrieved or assigned. Display an error message if the user attempts to assign or retrieve a score from a level that is out of range for the array of scores. Additionally, no level except the first one should be set unless the user has earned at least 100 points at each previous level. If a user…
