Write an inheritance hierarchy of three-dimensional shapes. Make a top-level shape interface that has methods for getting information such as the volume and the surface area of a three-dimensional shape. Then make classes and subclasses that implement various shapes such as cube, cylinders and spheres. Place common behavior in superclasses whenever possible, and use abstract classes as appropriate. Add methods to the subclasses to represent the unique behavior of each three-dimensional shape, such as a method to get a sphere’s radius.   Select three shapes from the list: sphere, cube, tetrahedron, cone, cylinder and  rectangular prisms.

Consider a three-dimensional (3-D) geometric shape as a concept. Any such 3-D shape will have a volume and surface area, but until you know the nature of the shape and its attribute dimensions, these will be abstract in nature. Design and implement an inheritance hierarchy starting with a 3-D shape, then a set of at least three derived classes that define regular 3-D shapes such as a cube, sphere, cylinder, and so on. Include with your submission a UML class diagram showing the design. Any general 3-D shape will have a name, but few other attributes. For each derived shape, store fundamental attribute data about its dimensions, and provide methods to access and modify this data. In addition, provide appropriate methods to compute each shape’s volume and surface area. For example, a cube has a volume of s3 where s is the length of a side, whereas a sphere has a volume of 4πr3/3 where r is the radius. In terms of style, every class should have constructors and a toString() method that…

Design a console program that will print details of DVDs available to buy. Make use of an abstract class DVD with variables that will store the title, yearReleased, running time and price of a DVD. Create a constructor that accepts the title, yearReleased and running time through parameters and assign these to the class variables. Create an abstract set method for the price of a DVD; also create get methods for the variables.Create a subclass InstructionalDVD that extends the DVD class and implements an iPrintable interface. The interface that must be added is shown below:public interface iPrintable { String ShowDetails();}The InstructionalDVD subclass has a private variable named category for which a get method must be written. The constructor of the InstructionalDVD class must accept the title, yearReleased, running time and category through parameters. Write the code for the setPrice() and ShowDetails() methods.Write a useDVD class and instantiate 2 objects of the InstructionalDVD…

This is for pygame Ball Class: The Ball class inherits from Drawable and it will draw a circle at its current location. You must implement at the very least the required methods of the base class (draw and get_rect), as well as a constructor. You may need to implement other methods as part of the public interface. This is the Drawable Class

• Create two subclasses for checking and saving accounts.A checking account has an overdraft limit, but a savings account cannot be overdrawn. Draw the UML diagram for the classes and then implement them. Write a test program that creates objects of Account, SavingsAccount, and CheckingAccount and invokes their toString() methods.

a:) Define a Polygon interface that has methods area() and perimeter(). b:) Then implement classes for Triangle, Quadrilateral, Pentagon, Hexagon, and Octagon, which implement this interface, with the obvious meanings for the area() and perimeter() methods. c:) Implement classes, IsoscelesTriangle, Equilateral-Triangle, Rectangle, and Square, which have the appropriate inheritance relationships. d:) Write a simple user interface, which allows users to create polygons of the various types, input their geometric dimensions, and then output their area and perimeter. e:) For extra effort, allow users to input polygons by specifying their vertex coordinates and be able to test if two such polygons are similar. using all a to e parts develop a program
