Project 1

Due: June 29, 2011

In this project you are asked to define some interfaces, abstract classes, and concrete classes, all placed in a specific package. You are also asked to demonstrate the use of the instanceof operator. If you don't use interfaces and/or instanceof you will not receive full credit. Submit to cs1302a on odin, a directory called Project1 (using the following command: submit Project1 cs1302a):

All the source code, i.e. .java files. Please do NOT include .class files. Comments are required in your source code! These comments should make it easy to read and follow the logic of your code. Also, your source code should be well formatted.
A README file telling us how to compile your program and how to execute it.

Project description:

Your program must be in package edu.uga.cs1302.vehicles.

Define an interface called Movable with methods:


int  getNoPassengers()
void setNoPassengers(int noPassangers)
int  getTopSpeed()
void setTopSpeed(int topSpeed)

Define an interface called Flyable with methods:


int getMaxAltitude()
void setMaxAltitude(int maxAltitude)
int getMaxRange()
void setMaxRange(int maxRange)

Define an interface called Floatable with methods:


int getTonnage()
void setTonnage(int tonnage)

Define an abstract class called Vehicle which must implement the Movable interface.
- Each Vehicle has a name
- Each Vehicle has a manufacturer
- Each Vehicle has a year of manufacture
- Keep count of the instances of the Vehicle class by using a static variable.
- If you believe you should define a variable as static, or final, or even both, do so and briefly mention the reason as a comment on that variable.
Define a class called Automobile, where an Automobile is-a subclass of Vehicle. Also, an Automobile has an engine with a given horsepower.
Define a class called Airplane, a subclass of Vehicle. Also, this class should implement the Flyable interface. Furthermore, an Airplane has a given number of engines.
Define a class called Ship, a subclass of Vehicle. Also, this class should implement the Floatable interface. Also, a Ship has a given shipping line owner.
Be creative and find more Vehicle kinds (at least two more). One of these new vehicle types (can be imaginary) should be able to both fly and float, and should be a direct subclass of Vehicle (for example, a flying boat, such as the PBY Catalina, manufactured years ago by Consolidated Aircraft).
Create three vehicles of each type, with different names and suitable attribute values (you may use fictitious values).
Store the Vehicle objects (above) in an array of type Vehicle.
Display a menu to the user on the screen (before implementing this part, read the notes below).
1. Press 1 to see how many vehicles are in the system.
2. Press 2 to see the name and kind of each vehicle.
3. Press 3 to see which vehicles can fly.
4. Press 4 to see which vehicles can float.
5. Press 5 to see which vehicles can float AND fly.
6. Press 6 to see a description of each vehicle.
7. Press h to see a brief help information for your system.
8. Press q to terminate the program.
Important notes about the menu:

If the user enters anything other than {1, 2, 3, 4, 5, 6, h, q}, the program should print a proper error message, and ask the user to enter a number between {1, 2, 3, 4, 5, 6} or the letters 'h' (for help) or 'q' (to quit). In other words, your program should not continue (or even worse, crash) if the user enters a wrong choice.
In option 1, the result should be the total number of instances of Vehicle class created so far (use a static variable).
For option 2, use instanceof to get kind.
For option 3, use instanceof. The result should contain both name (e.g., Mustang GT, Queen Mary 2, Boeing 777) and type (Automobile, Ship, etc) of the vehicle.
For option 4, use instanceof. The result should contain both name and type of the vehicle.
For option 5, use instanceof. The result should contain both name and type of the vehicle.
Option 6 above could display all attribute values for a given object. Note that the collection of properties should be suitable for a given type of a vehicle. For example:

Type: Automobile
Name: Mustang GT
Manufacturer: Ford
Manufacture year: 2010
Engine power: 315 hp
Number of passengers: 4
Top speed: 149 mph

Type: Airplane
Name: Boeing 777
Manufacturer: Boeing
Manufacture year: 2008
Number of engines: 2
Max altitude: 35000 ft
Max range: 6010 mi
Number of passengers: 440
Top speed: 590 mph

Type: Ship
Name: Queen Mary 2
Manufacturer: Chantiers de l'Atlantique
Manufacture year: 2004
Tonnage: 148528 tons
Owner: Cunard Line
Number of passengers: 2620
Top speed: 34 mph

Things to note:

Your program must be in package edu.uga.cs1302.vehicles.
Follow good coding style (proper variable names, indentation, etc).
Your design should be reasonably efficient, and in accordance with object oriented design principles (encapsulation, information hiding, inheritance, etc.).
If you are defining a variable as public or protected, briefly mention the reason for that.
If you are defining a variable as static or final, briefly mention the reason for that, as well.
