Question

In this exercise, you will be writing a simple java program to explore the decision making mechanism using if/else and switch statements.

The program is consists of one class (RentalCalculator). It will hold only one method, of course, in that case the name is main().
Write a Rental Amount Calculator Program for a Video Store. The rental amount will be calculated based on the following criteria:
a) The price of a regular DVD is $2.00. If rented on weekend, you have to pay another 25 cents extra per DVD.
The store also provides some discount based on the following:
b) If rented more than 5, there is a 20 cents discount per DVD.
c) If it is a special day (like Valentine’s day, Mother’s day...etc.,) , another 25 cents discount per DVD.
d) Discounts also given based on membership status. For VVIP, it is 15 cents. For VIP, it is 10 cents and for Regular member it is 5 cents per DVD.
e) Customer also has to pay 13% HST as usual.

Based on the above, determine the final rental amount and display the amount using two digits after the decimal point. The number of DVDs, weekend(y/n), special day(y/n) information, along with membership status (VVIP/VIP/REG) will be input from the keypad.

Answer 1

please give me an answer

Answer 2

To solve this problem and write a program to calculate the rental amount, you can follow these steps:

1. Declare variables: You will need variables to store the inputs, such as the number of DVDs, whether it's a weekend or a special day, and the membership status. Additionally, you will need variables to store the rental amount, any applicable discounts, and the total amount to be paid.

2. Get input from the user: Use the Scanner class in Java to prompt the user for input and store it in the appropriate variables.

3. Calculate the rental amount: Based on the given criteria, calculate the rental amount. Start with the price of a regular DVD, which is $2.00. If it's a weekend, add an additional 25 cents per DVD. Apply any applicable discounts based on the number of DVDs rented, special day, and membership status.

4. Calculate the HST: Multiply the rental amount by 13% to calculate the Harmonized Sales Tax (HST).

5. Calculate the total amount to be paid: Add the rental amount and the HST to calculate the total amount to be paid.

6. Display the result: Print the rental amount, HST, and the total amount to be paid, using two digits after the decimal point.

Here is a sample Java code implementation for the above steps:

```java
import java.util.Scanner;

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

// Step 1: Declare variables
int numberOfDVDs;
char weekend;
char specialDay;
String membershipStatus;
double rentalAmount;
double discount;
double hst;
double totalAmount;

// Step 2: Get input from the user
System.out.print("Enter the number of DVDs: ");
numberOfDVDs = scanner.nextInt();

System.out.print("Is it a weekend? (y/n): ");
weekend = scanner.next().charAt(0);

System.out.print("Is it a special day? (y/n): ");
specialDay = scanner.next().charAt(0);

System.out.print("Enter the membership status (VVIP/VIP/REG): ");
membershipStatus = scanner.next();

// Step 3: Calculate the rental amount
rentalAmount = 2.00; // Price of a regular DVD

if (weekend == 'y') {
rentalAmount += numberOfDVDs * 0.25; // Additional 25 cents per DVD for weekend
}

discount = 0;

if (numberOfDVDs > 5) {
discount += numberOfDVDs * 0.20; // 20 cents discount per DVD if rented more than 5
}

if (specialDay == 'y') {
discount += numberOfDVDs * 0.25; // Additional 25 cents discount per DVD for special day
}

switch (membershipStatus) {
case "VVIP":
discount += numberOfDVDs * 0.15; // 15 cents discount per DVD for VVIP member
break;
case "VIP":
discount += numberOfDVDs * 0.10; // 10 cents discount per DVD for VIP member
break;
case "REG":
discount += numberOfDVDs * 0.05; // 5 cents discount per DVD for regular member
break;
default:
System.out.println("Invalid membership status!");
return; // Exit the program if membership status is invalid
}

rentalAmount -= discount;

// Step 4: Calculate the HST
hst = rentalAmount * 0.13;

// Step 5: Calculate the total amount to be paid
totalAmount = rentalAmount + hst;

// Step 6: Display the result
System.out.printf("Rental Amount: $%.2f%n", rentalAmount);
System.out.printf("HST: $%.2f%n", hst);
System.out.printf("Total Amount: $%.2f%n", totalAmount);

scanner.close();
}
}
```

You can compile and run this Java program to calculate the rental amount based on the given inputs.
