A class called Book is designed (as shown in the class diagram) to model a book written by one author. It contains: Four private instance variables: name (String), price (double) static, and qty (int); Two constructors: public Book (String name, double price) { ...... } public Book (String name, double price, int qty) { ...... } getters/setters methods getName(), getPrice(), setPrice(), getQty(), setQty(). A toString() that returns book values.                                                          A class called Author is designed to model a book's author. It contains: Four private instance variables: name (String), email (String), and gender (char of either 'm' or 'f') and arrayList of Books. One constructor to initialize the name, email and gender with the given values; public Author (String name, String email, char gender) {......} public getters/setters. A toString() method that returns author object. A method addBook(Book b) which will add book in the Arraylist of books.…

Design a console program that will print details of DVDs available to buy. Make use of an abstract class DVD with variables that will store the title, yearReleased, running time and price of a DVD. Create a constructor that accepts the title, yearReleased and running time through parameters and assign these to the class variables. Create an abstract set method for the price of a DVD; also create get methods for the variables.Create a subclass InstructionalDVD that extends the DVD class and implements an iPrintable interface. The interface that must be added is shown below:public interface iPrintable { String ShowDetails();}The InstructionalDVD subclass has a private variable named category for which a get method must be written. The constructor of the InstructionalDVD class must accept the title, yearReleased, running time and category through parameters. Write the code for the setPrice() and ShowDetails() methods.Write a useDVD class and instantiate 2 objects of the InstructionalDVD…
class Point with instance variables as: xCoordinate(int) and yCoordinate(int). Write public instance methods (getters & setters) for each instance variable. Now, write a class Circle with private instance variables as radius and Pi (value is 3.14). Write public setter, getter for radius, Area method for calculating Area, Draw method for radius. Formula for calculating area=pi*r^2 Formula for calculating radius=Math.sqrt(xCordinate^2+yCordinate^2) Extend a Circle class from Point class such as Class Circle extends Point Write a Default constructor in Circle class that sets radius, xCoordinate&yCoordinate to some default value e.g. -1; Write a Parameterized constructor in Circle class which takes xCoordinate, yCoordinate and radius as a parameter. E.g. Circle (int xCoordinate, int yCoordinate, double radius) { this.xCoordinate= xCoordinate; this.yCoordinate= yCoordinate;…

Person and Customer Classes Write a class named (Person) with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named (Customer) that is a subclass of the (Person) class. The (Customer) class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the (Customer) class in a simple program.
