Question

Write an abstract superclass encapsulating a vehicle: A vehicle has two attributes: its owner's name and its number of wheels. This class has two non-abstract subclasses: one encapsulating a bicycle, and the other encapsulating a motorized vehicle. A motorized vehicle has the following additional attributes: its engine volume displacement, in liters; and a method computing and returning a measure of horsepower which is the number of liters times the number of wheels. Write an application class utilizing these two classes.

Answer 1

// Please find the below code.

package been;

public abstract class Vehicle {

   private String ownerName;
   private int numWheel;
  
  
   public Vehicle() {
       // TODO Auto-generated constructor stub
   }

   public Vehicle(String name, int num) {
      
       this.ownerName = name;
       this.numWheel = num;
      
   }
}

package been;

public class MotorizedVehicle extends Vehicle {

private String ownerName; // owner's name
private int numWheels; // number of wheels
private double engineSize; // engine size in litres

public MotorizedVehicle() {}

public MotorizedVehicle(String name, int wheels, double size) {
this.ownerName = name;
this.numWheels = wheels;
this.engineSize = size;
}

public String getOwnerName() {
return this.ownerName;
}

public int getNumWheels() {
return this.numWheels;
}

public double getEngineSize() {
return this.engineSize;
}

public double getHorsePower() {
return (this.engineSize * this.numWheels);
}
}
