Question

Objective: The objective of this lab is to get familiar with the syntax of the Java programming language. This lab is designed to reinforce programming concepts.

Instructions:

Description of the Problem.
A parking garage charges a $2.00 minimum fee to park for up to three hours. The garage charges an additional $0.50 per hour for each hour or part thereof in excess of three hours. The maximum charge for any given 24-hour period is $10.00. Assume that no car parks for longer than 24 hours at a time.

Write a Java application that calculates and displays the parking charges for each customer who parked in the garage yesterday. You should enter the hours parked for each customer. The program should display the charge for the current customer and should calculate and display the running total of yesterday’s receipts. The program should use the method calculateCharges to determine the charge for each customer.

Sample Output

Enter number of hours (a negative to quit): 2
Current charge: $2.00, Total receipts: $2.00
Enter number of hours (a negative to quit): 10
Current charge: $5.50, Total receipts: $7.50
Enter number of hours (a negative to quit): -1

Answer 1

// do comment if any problem arises

//code

import java.util.Scanner;

class charge {

    public double get_charge(int hours) {

        // if car is parked for 10 hours

        if (hours == 24)

            return 10.00;

        // initail charge of 2$

        double charge = 2.00;

        // if car has been parked for greater than 3 hours

        if (hours > 3)

            charge += (hours - 3) * 0.5;

        return charge;

    }

    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);

        double total = 0;

        // create a temporary object

        charge temp = new charge();

        while (true) {

            // read number of hours from user

            System.out.print("Enter number of hours (a negaitve to quit): ");

            int hours = sc.nextInt();

            // if user enters -ve break

            if (hours < 0)

                break;

            // calculate charge for given hours and display

            double current_charge = temp.get_charge(hours);

            total += current_charge;

            System.out.println("Current charge: $" + current_charge + ", Total reciepts: $" + total);

        }

    }

}

Output:

Enter number of hours (a negaitve to quit): 2 Current charge: $2.0, Total reciepts: $2.0 Enter number of hours (a negaitve to quit): 10 Current charge: $5.5, Total reciepts: $7.5 Enter number of hours (a negaitve to quit): -1,
