[Solved] CSC22100 Exercise1

1- Create a hierarchy of Java classes as follows:

MyLine is_a MyShape;

MyPolygon is_a MyShape; MyCircle is_a MyShape.

Class MyShape:

Class MyShapeis the hierarchys superclass and inherits the Java class Object. An implementation of the class defines a point (x, y) and the color of the shape. The class includes appropriate class constructors and methods, including methods that perform the following operations:

1. getX, getY, getColor returns the point (x, y) and color of the MyShape object;
2. setX, setY, setColor sets the point (x, y) and color for the MyShape object;
3. toString returns the objects description as a String. This method must be overridden in each subclass in the hierarchy.
4. draw draws a MyShape object. This method must be overridden in each subclass in the hierarchy. For the MyShape object, it paints the drawing canvas in the color specified.

Class MyLine:

Class MyLine inherits class MyShape. The MyLine object is a straight line defined by the endpoints (x₁, y₁) and (x₂, y₂). The MyLine object may be of any color. The class includes appropriate class constructors and methods that perform the following operations:

1. getLength returns the length of the MyLine object;
2. get_xAngle return the angle (in degrees) of the MyLine object with the x-axis;
3. toString returns a string representation of the MyLine object: length and angle with the x-axis;
4. draw draws a MyLine object whose end points are (x₁, y₁) and (x₂, y₂).

Class MyPolygon:

Class MyPolygon inherits class MyShape. The MyPolygon object is a regular polygon defined by the integer parameter, N the number of the polygons equal side lengths and equal interior angles, and the radius, r, in which it is inscribed. The MyPolygon object may be filled with a color. The class includes appropriate class constructors and methods that perform the following operations:

1. getArea returns the area of the MyPolygon object;
2. getPerimeter returns the perimeter of the MyPolygon object;
3. getAngle return the interior angle (in degrees) of the MyPolygon object;
4. getSide returns the side length of the MyPolygon object;
5. toString returns a string representation of the MyPolygon object: side length, interior angle, perimeter, and area;
6. draw draws a MyPolygon object whose center point (x, y) is defined in class MyShape and inscribed in a circle of radius r.

Class MyCircle:

Class MyCircle inherits class MyShape. The MyCircle object is defined by its radius, r, and center (x, y), and may be filled with a color. The MyCircle class includes appropriate class constructors and methods that perform the following operations:

1. getArea returns the area of the MyCircle object;
2. getPerimeter returns the perimeter of the MyCircle object;
3. getRadius returns the radius of the MyCircle object;
4. toString returns a string representation of the MyCircle object: radius, perimeter, and area;
5. draw draws a MyCircle object of radius r. The center point (x, y) of the circle is defined in class MyShape.

2- Use JavaFX graphics and the class hierarchy to draw a geometric configuration comprised of a sequence of alternating concentric circles and their inscribed hexagons as illustrated below, subject to the following additional requirements:

1. The code is applicable to canvases of variable height and width;
2. The dimensions of the shapes are proportional to the smallest dimension of the canvas;
3. The hexagons and circles are filled with different colors of your choice, specified through a MyColor enum class.

Explicitly specify all the classes imported and used in your Java code.
