Answer 1

public class Vehicle {

    private int wheels;
    private int mpg;

    public Vehicle(int wh, int miles) {
        wheels = wh;
        mpg = miles;
    }

    public String toString() {
        return ("Wheels: " + wheels + " Mpg: " + mpg);
    }
}

public class Car extends Vehicle {
    private static final int WHEELS = 4;

    public Car(int mpg) {
        // Fixed code here. call super.
        super(WHEELS, mpg);
    }
}

public class MotorCycle extends Vehicle {
    private static final int WHEELS = 2;

    public MotorCycle(int mpg) {
        // Fixed code here. call super.
        super(WHEELS, mpg);
    }
}

// Can't write output to this, because this code does not have a main method.
