Question

The program is described in Chapter 9, Exercise 11, in Programming Logic and Design. In this program, you should include two overloaded methods named computeRate(). One version accepts a number of days and calculates the rate at $99.99 per day.

The other accepts a number of days and a code for a meal plan. If the code is A, three meals per day are included, and the price is $169.00 per day. If the code is C, breakfast is included, and the price is $112.00 per day.

Each method returns the rate to the calling program where it is displayed. The main program asks the user for the number of days in a stay and whether meals should be included; then, based on the user’s response, the program either calls the first method or prompts for a meal plan code and calls the second method.

// Cornwall.java - This program computes hotel guest rates.

// Input:  Days in stay and meals included

// Output:  Hotel guest rate

import java.util.Scanner;

public class Cornwall

{

    public static void main(String args[])

    {

        Scanner input = new Scanner(System.in);

        int days;

        String dayString;

        String mealPlan;

        String question;

        double rate = 0.00;

        

        System.out.println("How many days do you plan to stay? ");

        

        dayString = s.nextLine();

        days = Integer.parseInt(dayString);

        System.out.println(" Do you want a meal plan? Y or N: ");

        question = s.nextLine();

        // Figure out which arguments to pass to the computeRate() method and

        // then call the computeRate() method

        if(question.equals("Y")) {

            System.out.println("Enter meal plan (A or C: )");

            

            rate = computerRate(days, mealPlan);

        }

        else {

            rate = computerRate(days);

        }

        

        System.out.println("The rate for your stay is: " + rate);               

        System.exit(0);

    } // End of main() method.

    

    

    // Write computeRate methods here.

    public static double computerRate(int x) {

        double rate = 99.99 * x;

        return rate;

    }

    public static double computerRate(int x, String plan) {

           double rate;

           if(mealPlan.equals("A")) {

               rate = 169 * x;

           }

           else if(mealPlan.equals("C")) {

               rate = 112 * x;

           }

           else {

               rate = 0;

           }

           return rate;

       }

} // End of Cornwall class.

I keep getting errors I can't figure it out, help please.
