I need to draw cars and trucks and background with road and a house with sky.

I have to use Vehicle class as a parent class. To draw pictures, i should draw fun things coming up with different drawings. the problem is that it is a "hard code".

I need to create a car class and a truck class as a children of Vehicle class.

the following UML classes shows the required elements in each class:

Vehicle class contains:

-x:int

-y:int

-color: Color

+Vehicle(in x:int, in y:int, in c:Color)

>>> Vehicle class to represent an automobile. there are 2 types of automobile: "car" and "truck". the draw method uses these values to draw the corresponding object.

>>> the draw() method is responsible of all the drawings of the Vehicles. it contains all the logic for drawing.

Car Class Contains:

-doors: int

+draw(in g:Graphics)

+Car(in x: int, in y: int, in c c:Color, in d: int)

+move()

>>> the move() methods move the car across the screen. it simply update the position of the car.

Truck Class Contains:

-type: string

+move()

+draw(in g: Graphics)

+Truck(in x: int, in y: int, in c:Color, in type: string)

DrawPanel Class Contains:

+paintComponent(in g: Graphics)

>>> the drawpanel class should contain Timer object that is responsible of making things move of all Vehicles that i create.

TestDraw class contains nothing its only runs the classes.
