Question

In Assignment 5, you will write a Toll Collection system. A toll collection system will provides the total cost of a truck and car when they exit the toll system.

Total cost for Trucks depends on:

1) the number of axles,

2) weight of the vehicle, and

3) total kilometres on the toll highway

Total cost for Cars depends on:

1) the number of axles,

2) total kilometres on the toll highway.

Below is the breakdown of the cost:

Trucks:

One-time cost per axle: $2

Charge per Km: $0.2 per km

Weight:

Less than 10,000 lbs: $0.003 per lbs

10,000 lbs - 20,000 lbs (inclusive): $0.0031 per lbs

Greater than 20,000 lbs: $0.0032 per lbs

Cars:

One-time cost per two axles: $3

Assume that all cars will have exactly 2 axles

Charge per Km: $0.25 per km

Classes:

You should have a Class for Truck and another class for Car with appropriate attributes that would help you calculate the toll price based on criteria above. Weight will be entered in Pounds (lbs) and distance will be entered in Kilometres (kms)

A Car object can be instantiated using Car nissan = new Car(36.2) - The distance is provided in the parameter.

Total cost for the Car instantiated above should be:
One-time Cost: $3.0

Distance cost: 36.2*0.25 = $9.05

Total = $12.05

A Truck object can be instantiated using Truck mack = new Truck(5, 21000, 65.0) - The number of axles in the first parameter, the weight of the truck in the second parameter, and finally, the distance in the third parameter.

Total cost for a Truck instantiated above should be:
Axle cost: 5*2 = $10

Weight cost: 21000*0.0032 = $67.20

Distance cost: 65.0*0.2 = $13

Total = $90.2

In addition to the Truck and Car classes, you will have a Class called Assignment 5 which will have the main() method. I am providing three sample Assignment5.java for you to test. Your Truck and Car classes MUST work with the below example. You are welcome to create helper methods in Truck and Car classes. You MUST have the right checks in both Truck and Car classes to ensure the program won't throw exceptions or return incorrect values. Additionally, if values provided is < 0 (for axles) and < 0.0 (for kms and distance), you should default the value to 0 (for axles) and 0.0 (for kms and distance).

// Sample Assignment5.java

public class Assignment5 {

    public static void main(String[] args) {

        Truck mack1 = new Truck(5, 21000.0, 65.0);
        Truck mack2 = new Truck(6, 22000.4, 15.3);
        Truck mack3 = new Truck(3, 2949.4, 19.0);

        double mack1Cost = mack1.getCost();
        double mack2Cost = mack2.getCost();
        double mack3Cost = mack3.getCost();

        System.out.printf("$%.2f", mack1Cost + mack2Cost + mack3Cost);
        // should output $194.31
    }
}

// Sample Assignment5.java

public class Assignment5 {

    public static void main(String[] args) {

        Truck mack1 = new Truck(5, 21000.0, 65.0);
        Car nissan1 = new Car(36.2);

        double mack1Cost = mack1.getCost();
        double nissan1Cost = nissan1.getCost();

        System.out.printf("$%.2f", mack1Cost + nissan1Cost);
        // should output $102.25
    }
}

// Sample Assignment5.java

public class Assignment5 {

    public static void main(String[] args) {

        Truck mack1 = new Truck(5, 21000.0, 65.0);
        Car nissan1 = new Car(36.2);
        Car nissan2 = new Car(16.2);

        double mack1Cost = mack1.getCost();
        double nissan1Cost = nissan1.getCost();
        double nissan2Cost = nissan2.getCost();

        System.out.printf("$%.2f", mack1Cost + nissan1Cost + nissan2Cost);
        // should output $109.30
    }
}
