Library needs to automate the manual process of issue and receipt of books.To begin with, the developer needs to develop a class Book and a class Magazine.

Help the developer to develop this class.

NOTE: A partial code has been given. Do the additions wherever necessary to satisfy the above requirements.

Java Class : Book (Constructor)

protected ISBNNumber - int

protected bookName - String

protected price - double

constructor - Book(int,String,double)

constructor - Book

getISBNNumber() int

setISBNNumber() int void

getBookName() String

setBookName() String void

getPrice() double

setPrice() double void

calculateDiscount() double

Java Class : Magazine (constructor)

constructor Magazine(int,String,double,String)

constructor Magazine()

getMagazineType() String

setMagazineType() String void

calculateDiscount() double

develop a public class Book with protected attributes :

int ISBNNumber

String bookName

double price

Include appropriate public getters and setters method.

develop a public 3 argument constructor with arguments - ISBNNumber, bookName and price.

develop a method calculateDiscount() in Book class as,

public float calculateDiscount() - This method will not be implemented in Book class. Make this method as abstract. Also make the class Book as abstract class.

develop a public class Magazine with private attributes :

String magazineType

Include appropriate public getters and setters method.

This class Magazine should inherit the Book class.

Write a public 4 argument constructor with arguments - ISBNNumber, bookName, price and magazineType.

Override the calculateDiscount() method as mentioned below.

public float calculateDiscount() - This method should return 15% of the price.

Example if the book price is 1500, then this method should calculate the discount as 15% of 1500 = 225 should be returned.

Create a public class Main which has the main method. Create the object for Magazine and check for its correctness as shown in the sample input and output.

Note : All classes and methods needs to be declared as public

Sample Input :

Enter the ISBN Number

5128

Enter the Book Name

Thinking in Java

Enter the price

1500

Enter the magazine Type

Weekly

Sample Output :

ISBN Number 5128

Discount Amount 225

---------------------------------------------------------------------------------------------------------

public class Main {

public static void main(String[] args) {

Scanner sc=new Scanner(System.in);

System.out.println("Enter the ISBN Number");

int isbnnum= sc.nextInt();

sc.nextLine();

System.out.println("Enter the Book Name");

String name=sc.nextLine();

System.out.println("Enter the price");

double price=sc.nextDouble();

System.out.println("Enter the magazine Type");

String type = sc.next();

//Uncomment these lines after performing the necessary changes in Book and Magazine class

/*

Magazine magazine =new Magazine(isbnnum,name,price,type);

double discount = magazine.calculateDiscount();

System.out.println("ISBN Number "+isbnnum);

System.out.println("Discount Amount "+discount);

*/

}

}

//Make the necessary changes to make this class abstract

public class Book {

protected int ISBNNumber;

protected String bookName;

protected double price;

public Book(int ISBNNumber, String bookName, double price) {

this.ISBNNumber = ISBNNumber;

//Getters and Setters

public int getISBNNumber() {

public void setISBNNumber(int iSBNNumber) {

}

public String getBookName() {

return bookName;

}

public void setBookName(String bookName) {

this.bookName = bookName;

}

public double getPrice() {

return price;

}

public void setPrice(double price) {

this.price = price;

}

//Make this method calculateDiscount() as abstract

//public double calculateDiscount()

}

-------------------------------------------------------------------------------------------------------------------------------------------

//Make the necessary changes to make this class inherit the Book class

public class Magazine

{

private String magazineType;

//Constructor

public Magazine(int ISBNNumber, String bookName, double price,String magazineType) {

//Uncomment the below statement after you inherit the Book class

//super(ISBNNumber,bookName,price);

this.magazineType=magazineType;

}

public Magazine()

{

}

//Getters and Setters

public String getMagazineType() {

return magazineType;

}

public void setMagazineType(String magazineType) {

this.magazineType = magazineType;

}

//Override the calculateDiscount() method to return 15% of price

// public double calculateDiscount() {

// }

}
