Question

Making use of object orientation write a program that stores and evaluates the total cost for items bought from a supermarket. The cashier should enter the following: - Product code, Price and Quantity. The total price should be evaluated as follows: -

Total cost = Price * Quantity

If the total cost per item is more than 20,000 there is a discount of 14% on that item and a discount of 10% on an item whose total cost is between 10,000 and 20,000. No discount is given on items whose total cost is less than 10,000

Answer 1

import java.util.*;


class App {


	public static void main(String[] args) {
		Scanner keyboard = new Scanner(System.in);
		System.out.print("Enter the product code: ");
		String code = keyboard.nextLine();
		// Product code, Price and Quantity.
		System.out.print("Enter the product price: ");
		double price = keyboard.nextDouble();
		System.out.print("Enter the product quantity: ");
		int quantity = keyboard.nextInt();
		double totalCost = price * quantity;
		double discount = 0;
		if (totalCost >= 20000) {
			discount = totalCost * 0.14;
		} else if (totalCost >= 10000 && totalCost < 20000) {
			discount = totalCost * 0.1;
		}


		System.out.println("The product code: " + code);
		System.out.println("The product total cost: " + totalCost);
		System.out.println("The discount: " + discount);
		totalCost -= discount;
		System.out.println("The total cost: " + totalCost);


		keyboard.close();
	}
