Write a collection of classes to describe the following shapes:

Rectangle

Square

Circle

Cylinder

Cube

Shape Characteristics

The shapes have the following characteristics:

All shapes have a description that defines the shape.

All shapes have a method that calculates the area.

For two-dimensional shapes, the area is returned.

For three-dimensional shapes, the surface area is returned.

Two-dimensional shapes have a method that returns the perimeter.

Three-dimensional shapes have a method that returns the volume.

Class Design

Think carefully about how to structure the classes. Follow the design principles listed below. You can create an additional parent class and interfaces, as needed.

Each class should meet the properties defined above. In addition, each class should have (either directly or through inheritance):

(1) variables to describe size, as appropriate for each shape

Limiting size variables to only integer values is okay.

(2) constructor

(3) getters and setters

You can choose not to allow setters. If you allow setters, include validity checks where appropriate.

(4) a getDescription method that returns the shape definition

(5 ) a toString method that returns all text definitions that apply to the shape and size variables

(6) an equals method: two shapes are the same if they have the same description and the same size

Note that for the Rectangle class, the rectangle (3,4) should be considered the same as the rectangle (4,3)

(7) a perimeter, area, and volume method, as appropriate for each shape, as described above

You will also write two additional methods:

(8 In Cylinder, write a method that takes in a Circle and determines if that circle could be a top/bottom of of the current cylinder (meaning it has the same size).

(9) In Cube, write a method that takes in a Square and determines if that square could be one side of the current Cube (meaning it has the same size).

I have provided a driver program and the sample output you should obtain when you run the program.

(10 ) The driver program is missing code. Fill in that missing code.

Design Principles

You will be graded both on your syntax but also your class design. For full credit, follow good principles of programming, object-oriented design, and inheritance. Also consider these design elements:

For all required methods, your class can either include the method directly or inherit it. Think about where the method logically belongs.

Think about what the parent-child relationship should be between the classes.

Think about what classes should be abstract.

Think about what interfaces you should create.

Move common code as high up in the hierarchy as possible.

Use super whenever possible.

Avoid repeated code.

Follow appropriate naming and style conventions.

Follow good principals of object-oriented design and inheritance.

After

Write a canFitInside method that determines if one ThreeDimensional shape can fit inside of another (this would be true if the volume of the outer were greater than the volume of the inner). Carefully consider where this method belongs.

Update the driver program to add an additional test to output any nested shapes.
