Consider the class hierarchy in Exercise 1.
1- Amend the hierarchy of Java classes in Exercise 1 as follows:
MyPolygon is_a MyShape;
MyRectangle is_a MyShape
MyOval is_a MyShape;
MyCircle is_a MyOval;
2- Interface MyShapeInterface, interface MyPositionInterface, and interface MyShapePositionInterface are specified in connection with the class hierarchy.
3- Interface MyShapeInterface includes appropriate abstract, static, and/or default methods that describe the intrinsic functions and behaviors of the specific object types of the class hierarchy, including:
a. getArea — describes the area of an object in the class hierarchy;
b. getPerimeter — describes the perimeter of an object in the class hierarchy.
4- Interface MyPositionInterface includes appropriate abstract, static, and/or default methods that describe the positional functions and behaviors of the specific object types of the class hierarchy, including:
a. getPoint – returns the point (x, y);
b. moveTo – moves point (x, y) to point (x + x, y + y);
c. distanceTo – returns distance from point (x, y) to a point;
5- The abstract class MyShape implements interface MyShapePositionInterface which extends interface MyShapeInterface and interface MyPositionInterface. Interface MyShapePositionInterface includes appropriate abstract, static, and/or default methods that describe the functions and behaviors of the specific object types of the class hierarchy, including:
a. getBoundingBox — returns the bounding rectangle of an object in the class hierarchy;
b. doOverlap — returns true if two objects in the class hierarchy overlap.
6- Use JavaFX graphics and the class hierarchy to build a class Application that processes polymorphically the subclasses in the hierarchy to draw the geometric object shown, subject to the following additional requirements:
a. The code is applicable to canvases of variable height and width;
b. The dimensions of the shapes are proportional to the smallest dimension of the canvas;
c. The rectangles and ovals are filled with different colors of your choice.
