Problem statement
You want to buy a used car, but need help deciding, so you create a formula that will help you rate available used cars, given their characteristics and some user reviews that you find online:
Score = (26,000 – Price)/3000 – 0.2*(Years old) + 0.2*(MPG-25) + Driver rating
Assume that the Driver rating for a car is (G + (0.5*O) - B)/T, where G, O, B, and T are the number of Good, OK, Bad ratings, and Total number of ratings, respectively.

Toyota Honda Chevrolet BMW
Price 18,000 20,000 17,000 26,000
Years old 0.5 1 1 4
MPG 26 25 27 23

Driver rating Toyota Honda Chevrolet BMW
Bad 3 1 1 0
OK 2 2 4 1
Good 1 6 5 3

Program
Your assignment is to write a program containing classes and objects to decide which car to buy. You will need the following classes:
-A UsedCarLot class
-A Car class
-A DriverRating class
- A test class that only has a main() method to create and use the necessary objects.

The UsedCarLot class has space for four Car items. Each Car has a DriverRating object that contains the breakdown of the ratings given by reviewers. You must have a DriverRating class; you may not put the ratings directly in the Car class.

Your main() method does not need to accept any user inputs. All data can be hard-wired into the program. Add additional methods as appropriate in the classes listed above to enable your main() method to accomplish the following tasks.

Create the necessaryUsedCarLot, Car and DriverRating objects. Create each object using the data in the tables from the Problem Statement section above.
Call a method in the appropriate class that will give the driver rating for each of the cars and output the result to the console. For this part, access the Car objects through the UsedCarLot object.
Call a method in the appropriate class that will compute the overall score for a given car. Call
this for each Car and output the result. For this part, access the Car objects directly.
You read more reviews online, one Bad review for Chevrolet and three Good reviews for BMW. Call a method in the appropriate class that will update the appropriate data. Output the new overall scores for these two Cars.
Call a method that prints the make of the Cars in the UsedCarLot with an age of one year old or less, out of the set of four cars.
Some people will want to avoid “lemons”. Call a method that returns the percentage of bad reviews for each car.

Your UsedCarLot, Cars and DriverRating classes must have the appropriate data members, constructors, getXXX() methods, setXXX() methods and other methods in order to complete the assignment. All data members must be private in all classes. You only need to write the getXXX(), setXXX() and other methods required to produce the specific outputs for this homework, as described above. You are welcome to use arrays if you are comfortable with them; they are not required for this assignment.

Example Output:
Driver ratings:
Toyota: -0.16666666666666666
Honda: 0.6666666666666666
Chevrolet: 0.6
BMW: 0.875

Over all scores: Toyota: 2.6
Honda: 2.466666666666667
Chevrolet: 3.8
BMW: -0.325

With 1 additional bad review, the updated overall score for Chevrolet is: 3.654545454 With 3 additional good reviews, The updated overall score for BMW is: -0.2714285714

Cars in lot newer than one year: Toyota
Honda Chevrolet

Percent of bad ratings: Toyota: 50.0%
Honda: 11.11111111111111%
Chevrolet: 18.181818181818183%
BMW: 0.0%
