Question 1
Using C# create a class called shapes, the class is supposed to have attributes length, width and height. There should be methods for calculating the area and the perimeter of a shape. Create classes circle, rectangle and square to inherit from class shapes. The derived classes should override methods in the parent class for them to calculate their own areas and perimeters.

- PLZ help In Javaarrow_forward{In Java Programming Please} Create a class hierarchy that represents different types of employees in a company. Start with a class called Employee that has two methods: calculateSalary() and displayDetails(). Then, create two subclasses of Employee: Manager and Engineer. Override the calculateSalary() method in both subclasses to calculate the salary based on their job role and experience. Override the displayDetails() method in both subclasses to print out a message indicating the details of the employee. Next, create another class called Salesperson that extends Employee and has a method called calculateCommission(). Create two subclasses of Salesperson: SeniorSalesperson and JuniorSalesperson. Override the calculateCommission() method in both subclasses to calculate the commission based on their sales performance. Override the displayDetails() method in both subclasses to print out a message indicating the details of the salesperson.

- 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.arrow_forwardC- Create the sub class UsedBook that is derived from the super class Book and has the following instance variables, constructor, and functions: title ( String) isbn ( String) authors (String) publisher (String) edition ( int) published_year (int) price_new (double) // the price of the book if it is new age (int) // how old the book is in years Constructor that takes all of the above variables as input parameters. set/get functions calculate_price method // the price is calculated as price_new * (1- 0.10*age) print function that prints all information related to the old book.
