(iii) void calculate() — To calculate the price after discount. Discount is calculated based on the following criteria.

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

        price = scanner.nextDouble();

        scanner.close();

    }

    // To calculate the price after discount based on the given criteria

    public void calculate() {

        if (price <= 1000) {

        } else {

        }

    }
