A square shaped can be considered to be a specific type of a rectangle. This is a relationship we can "is-a", where a square "is-a" specific type of rectangle, particularly when all 4 sides are equal. In OOP this relationship is called Inheritance.
The same idea we can follow for a circle, which "is-a" specific type of an oval.
We can also generalize where we can say all circles, ovals, squares and rectangles are different types of shapes.
Hence, shape is a general class. But can you draw a shape without knowing what specific shape you want to draw? thus a shape is what we call in OOP an abstract class - that is a class that cannot be instantiated.
However, in the spirit of programming in general, we want to create a shape factory where we can generate random shapes (with valid dimensions, i.e. no negative or zero sides or radius, and keep max dimension to 100, all integers).
Furthermore, adding one twist, if we have a canvas object, one can say that the canvas contains shapes or "has-a" list of shapes associated with it. This is a composition association in OOP, where a canvas contains, or "has-a" shape(s).
Shape is abstract class, and every shape has a unique id (an incrementing positive integer- Hint: use a static counter variable for this).
An Oval has a horizontal radius and a vertical radius. An Oval is a Shape.
A Circle is a specific type of Oval.
A Rectangle is a Shape with a value for length and width.
A Square is a Rectangle.
A Canvas has a list of 10 random Shape(s). There should be no duplicate shapes (ie. same dimensions of the same shape).
A Main instantiates a Canvas and displays its contents (in text as the example below:)
>> Canvas has the following random shapes:
Shape 1: RECTANGLE 4x10
Shape 2: SQUARE 50x50
Shape 3: CIRCLE 100
Shape 4: OVAL 100x40
Shape 5: OVAL 10x11
Shape 6: CIRCLE 10
Shape 7: SQUARE 1x1
Shape 8: RECTANGLE 1x2
Shape 9: RECTANGLE 2x2
Shape 10: CIRCLE 11
For this assignment you are to implement the classes: CShape, CCanvas, COval, CCircle, CRectangle and CSquare. [2 pts each =6 pts]
Then a main method (with driver class) to instantiate a Canvas containing 10 random non-duplicate shapes and printing them (as per example above).[4 pts]
You must fully document every class, method, and attribute following the conventional JavaDoc. [-2 if not followed properly/0 marks on assignment if no proper documentation].
