Define a class named BookFair with the following description:

Instance variables/Data members:
String Bname — stores the name of the book
double price — stores the price of the book

Member methods:
(i) BookFair() — Default constructor to initialize data members
(ii) void Input() — To input and store the name and the price of the book.
(iii) void calculate() — To calculate the price after discount. Discount is calculated based on the following criteria.

Price Discount
Less than or equal to ₹1000 2% of price
More than ₹1000 and less than or equal to ₹3000 10% of price
More than ₹3000 15% of price

(iv) void display() — To display the name and price of the book after discount.

Write a main method to create an object of the class and call the above member methods.

Program:

import java.util.Scanner;

public class BookFair
{
    private String bname;
    private double price;

    public BookFair() {
        bname = "";
        price = 0.0;
    }

    public void input() {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter name of the book: ");
        bname = in.nextLine();
        System.out.print("Enter price of the book: ");
        price = in.nextDouble();
    }

    public void calculate() {
        double disc;
        if (price <= 1000)
            disc = price * 0.02;
        else if (price <= 3000)
            disc = price * 0.1;
        else
            disc = price * 0.15;

        price -= disc;
    }

    public void display() {
        System.out.println("Book Name: " + bname);
        System.out.println("Price after discount: " + price);
    }

    public static void main(String args[]) {
        BookFair obj = new BookFair();
        obj.input();
        obj.calculate();
        obj.display();
    }
}

Output:

Enter name of the book: Java the ultimate
Enter price of the book: 2081
Book Name: Java the ultimate
Price after discount: 1872.9
