You need to implement a Car rental system implemented in java using object-oriented programming.

Customers can:

● See available Cars (100 cars in total)

● Rent cars on hourly basis RMB100 per hour.

● Rent cars on a daily basis RMB400 per day.

● Rent cars on a weekly basis RMB1000 per week.

● Buy car insurance (price will depend on the duration and should be calculated based on the time the car was rented for RMB5 per hour e.g., for one day 24*5=120).

● Rent more than one car at one time

The car rental company should:

● Show the amount owed when the customer returns the car.

● Issue an invoice for the amount owed with separate field for insurance.

● Display available inventory (number of cars available).

● Take requests on hourly, daily, and weekly basis by cross verifying stock.

For simplicity, you can assume that:

● Any customer requests rentals of only one type i.e., hourly, monthly, or weekly

● Customers are free to choose the number of cars they want

● Requested cars should be less than available stock

Test Scenarios:

You should record your screen when running the following tests and submit a video inside the zip file. The video deration should be less than two minutes and you should explain by talking to the microphone during the recording.

1- The customer tries to rent 4 cars for one day and will be billed for RMB1600.

2- The customer tries to rent 4 cars for one day and buy insurance so will be billed for RMB1600 plus the insurance fee RMB480.

3- The customer tries to rent more cars than available and receives an error: “We do not have enough cars”.

Bonus Point (10% Extra):

To get the extra 10% the rental system should have a Graphical User Interface (GUI) to allow the users interact with it. Here is a Tutorial and a video guide on creating GUIs in IntelliJ Swing.

Grade component

Project submission (50% of full grade).

Submission deadline

The submission deadline is Wednesday, November 30, 2022, at 23:59 hours (Dublin time).

Submission guidelines

Your submission should include:

● Source-code of your implementation application, implemented in java. You should submit your code as a project and not as a single file. For this you should export your project as a zip file from the IDE (See how to do it on IntelliJ).

● The screen recording of test scenarios (less than 2 minuets). If you have a GUI you should also record the test scenarios using that.
