Question

13.2 Write a class that specifies the characteristics of a car, like a type (sedan, jeep, mini, SUV, etc), gear (auto, manual), maximum speed (mph), average fuel consumption (mpg), etc. Create a few objects to illustrate your desired cars.

Answer 1

public class Car {

    private String type;
    private String gear;
    private double maxSpeed;
    private double averageFuelConsumption;

    public Car() {
    }

    public Car(String type, String gear, double maxSpeed, double averageFuelConsumption) {
        this.type = type;
        this.gear = gear;
        this.maxSpeed = maxSpeed;
        this.averageFuelConsumption = averageFuelConsumption;
    }

    public String getType() {
        return type;
    }

    public void setType(String type) {
        this.type = type;
    }

    public String getGear() {
        return gear;
    }

    public void setGear(String gear) {
        this.gear = gear;
    }

    public double getMaxSpeed() {
        return maxSpeed;
    }

    public void setMaxSpeed(double maxSpeed) {
        this.maxSpeed = maxSpeed;
    }

    public double getAverageFuelConsumption() {
        return averageFuelConsumption;
    }

    public void setAverageFuelConsumption(double averageFuelConsumption) {
        this.averageFuelConsumption = averageFuelConsumption;
    }

    @Override
    public String toString() {
        return "type='" + type + '\'' + ", gear='" + gear + '\'' +
                ", maxSpeed=" + maxSpeed + ", averageFuelConsumption=" + averageFuelConsumption;
    }
}

class CarTest {

    public static void main(String[] args) {
        Car car1 = new Car("SUV", "auto", 85, 20);
        Car car2 = new Car("jeep", "manual", 100, 25);
        Car car3 = new Car("sedan", "auto", 75, 32);

        System.out.println(car1);
        System.out.println(car2);
        System.out.println(car3);
    }
}
