Question

Chapter 5. PC #2. Retail Price Calculator (page 312)

Write a program that asks the user to enter an item’s wholesale cost and its markup percentage. It should then display the item’s retail price. For example:

• If an item’s wholesale cost is 5.00 and its markup percentage is 100 percent, then the item’s retail price is 10.00.

• If an item’s wholesale cost is 5.00 and its markup percentage is 50 percent, then the item’s retail price is 7.50.

The program should have a method named calculateRetail that receives the wholesale cost and the markup percentage as arguments, and returns the retail price of the item.

Class name: RetailPriceCalculator

Here is a working code: please modify this code so it works in Hypergrade when I submit it so it passes all the test casses in Hypergrade.Because right now when I upload it to Hypergrade it says 0 out of 5 casses pased. It has to pass all the test casses in Hypergrade Please fix this code. I do not need thanks for playing or goodbye in the program.

import java.util.Scanner;

public class RetailPriceCalculator {
public static void main(String[] args) {
Scanner keyboard = new Scanner(System.in);

while (true) {
double wholesaleCost = getWholesaleCost(keyboard);
if (wholesaleCost == -1) {
break;
}

double markupPercentage = getMarkupPercentage(keyboard);
if (markupPercentage == -1) {
break;
}

double retailPrice = calculateRetail(wholesaleCost, markupPercentage);
System.out.printf("The retail price is: %.2f%n", retailPrice);
}

keyboard.close();
}

public static double getWholesaleCost(Scanner keyboard) {
System.out.println("Please enter the wholesale cost or -1 to exit:");
double cost = keyboard.nextDouble();
if (cost == -1) {
return -1;
} else if (cost < 0) {
System.out.println("Wholesale cost cannot be a negative value.");
return getWholesaleCost(keyboard);
}
return cost;
}

public static double getMarkupPercentage(Scanner keyboard) {
System.out.println("Please enter the markup percentage or -1 to exit:");
double percentage = keyboard.nextDouble();
if (percentage == -1) {
return -1;
} else if (percentage < -100) {
System.out.println("Markup cannot be less than -100%.");
return getMarkupPercentage(keyboard);
}
return percentage;
}

public static double calculateRetail(double wholesaleCost, double markupPercentage) {
return wholesaleCost * (1 + markupPercentage / 100);
}
}
