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 code: please modify this code so it works in Hypergrade when I submit it so it passes all the test casses in Hypergrade. It has to pass all the test casses in Hypergrade becausw when I submit the code in Hypercase it does not run and it says 0 out of 5 casses passed. Please fix this code. I do not need thanks for playing or goodbye in the program. import java.io.File; import java.io.FileNotFoundException; import java.util.Scanner; public class FileRead { public static void main(String[] args) throws FileNotFoundException { Scanner keyboard = new Scanner(System.in); System.out.println("Please enter the file name or type QUIT to exit:"); String filename = keyboard.nextLine(); if (filename.equalsIgnoreCase("Quit")) return; File myFile = new File(filename); while (!myFile.exists()) { System.out.println("File: " + filename + " does not exist."); System.out.println("Please enter the file name again or type QUIT to exit:"); filename = keyboard.nextLine(); if (filename.equalsIgnoreCase("Quit")) { return; } myFile = new File(filename); } Scanner inputFile = new Scanner(myFile); int lines = 0; while (inputFile.hasNext()) { String str = inputFile.nextLine(); lines++; System.out.println(lines + ": " + str); } inputFile.close(); } } Test Case 1 Please enter the wholesale cost or -1 exit:\n 10ENTER Please enter the markup percentage or -1 exit:\n -1ENTER Test Case 2 Please enter the wholesale cost or -1 exit:\n 100ENTER Please enter the markup percentage or -1 exit:\n 100ENTER The retail price is: 200.00\n Please enter the wholesale cost or -1 exit:\n -1ENTER Test Case 3 Please enter the wholesale cost or -1 exit:\n 10ENTER Please enter the markup percentage or -1 exit:\n 50ENTER The retail price is: 15.00\n Please enter the wholesale cost or -1 exit:\n 10ENTER Please enter the markup percentage or -1 exit:\n 100ENTER The retail price is: 20.00\n Please enter the wholesale cost or -1 exit:\n 10ENTER Please enter the markup percentage or -1 exit:\n -100ENTER The retail price is: 0.00\n Please enter the wholesale cost or -1 exit:\n -1ENTER Test Case 4 Please enter the wholesale cost or -1 exit:\n -200ENTER Wholesale cost cannot be a negative value.\n Please enter the wholesale cost again or -1 exit:\n 10ENTER Please enter the markup percentage or -1 exit:\n -200ENTER Markup cannot be less than -100%.\n Please enter the markup again or -1 exit:\n 50ENTER The retail price is: 15.00\n Please enter the wholesale cost or -1 exit:\n -1ENTER Test Case 5 Please enter the wholesale cost or -1 exit:\n -1ENTER
