Car Subclass

Purpose:

The Car class represents a specific type of vehicle with unique attributes and behaviors specific to cars.

Attributes:

numberOfDoors $($int$)$: Represents the number of doors on the car. This attribute should be private to Car.

Constructor:

A constructor that takes speed, fuel, and numberOfDoors as parameters. It should call the Vehicle constructor to initialize speed and fuel, and set numberOfDoors.

Methods:

start$()$: Override the start$()$ method to print a custom message indicating that the car has started. Students should decide if they want to call the Vehicle class$$s start$()$ method as part of this method.

honk$()$: A method that prints a message indicating the car horn sound, such as $$Beep Beep!$$

Additional Considerations:

Add getter and setter methods for numberOfDoors if students plan to modify this attribute outside of the class.

Bicycle Subclass

Purpose:

The Bicycle class represents a specific type of vehicle with unique attributes and behaviors specific to bicycles.

Attributes:

hasBell $($boolean$)$: Represents whether the bicycle has a bell. This attribute should be private to Bicycle.

Constructor:

A constructor that takes speed, fuel, and hasBell as parameters. It should call the Vehicle constructor to initialize speed and fuel, and set hasBell.

Methods:

start$()$: Override the start$()$ method to print a custom message indicating that the bicycle has started. This message could include something specific to bicycles, such as "Pedal away!"

ringBell$()$: A method that checks if hasBell is true. If it is$,$ print a message indicating the bell sound, like "Ring Ring!" If hasBell is false, print a message indicating the bicycle has no bell.

Additional Considerations:

Add getter and setter methods for hasBell if students plan to modify this attribute outside of the class.

Main Class

Purpose:

The Main class is the driver class for the project. In this class, students will create instances of Car and Bicycle and test their methods.

Instructions for Main Class:

Create a Car Object: Instantiate a Car object, passing in values for speed, fuel, and numberOfDoors.

Test the methods by calling start$(),$ displayFuel$(),$ and honk$()$ on the Car object.

Create a Bicycle Object: Instantiate a Bicycle object, passing in values for speed, fuel, and hasBell.

Test the methods by calling start$(),$ displayFuel$(),$ and ringBell$()$ on the Bicycle object.

Additional Tasks for Students:

Experiment with creating different Car and Bicycle objects with varied values for the attributes.

Test the effects of access specifiers by attempting to access attributes and methods directly from Main.
