Solution

TC++ #7316

import java.util.Scanner;

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

public BookFair() {
Bname = null;
price = 0.0;
}

public void Input() {
Scanner scanner = new Scanner(System.in);
System.out.print("Enter book name: ");
Bname = scanner.nextLine();
System.out.print("Enter price: ");
price = scanner.nextDouble();
}

public void calculate() {
double discountPercentage = 0;
if (price <= 1000) { discountPercentage = 2; } else if (price > 1000 && price <= 3000) { 25 discountPercentage = 10; 26 } else if (price > 3000) {
discountPercentage = 15;
}
price = price - (price * discountPercentage / 100);
}

public void display() {
System.out.println("Name: " + Bname);
System.out.println("Price after discount: " + price);
}
public static void main(String[] args) {
BookFair bookFair = new BookFair();
bookFair.Input();
bookFair.calculate();
bookFair.display();
}
}

Sample output
