Explanation / Answer

public class Engine {

    public Engine(int cylinders, int horsePower) {
        this.cylinders = cylinders;

    }

    public String toString() {
        return " **Engine Information**"
                + "   Cylinders   : " + this.getCylinders()
                + "   Horse Power : " + this.getHorsePower();
    }

    public int getCylinders() {
        return cylinders;
    }

    public void setCylinders(int cylinders) {
        this.cylinders = cylinders;
    }

        this.horsePower = horsePower;
    }
}
