CMSC335 Project 1

Overview

In the project you will use Java Inheritance to create a series of related classes with a “Shape” theme.

Before completing this exercise, be sure to review and try the Java class and inheritance examples and

materials found in this free Safari resource:

You should focus on Chapters 6, 7 and 8.

Note: Be sure to review is-a and has-a class relationships prior to starting this exercise as well.

Assignment Details

Design, implement and test a Java class Inheritance hierarchy that would satisfy the following is-a and

has-a relationships:

 A Shape is an object

 A TwoDimensionalShape is a Shape

 A ThreeDimensionalShape is a Shape

 A Circle is a TwoDimensionalShape

 A Square is a TwoDimensionalShape

 A Triangle is a TwoDimensionalShape

 A Rectangle is a TwoDimensionalShape

 A Sphere is a ThreeDimensionalShape

 A Cube is a ThreeDimensionalShape

 A Cone is a ThreeDimensionalShape

 A Cylinder is a ThreeDimensionalShape

 A Torus is a ThreeDimensionalShape

 A Shape has a NumberofDimensions

 A TwoDimensionalShape has an area

 A ThreeDimensionalShape has a volume

Note you should fill in additional methods and variables that make sense for each of the classes. Also

some assumptions about shape types is appropriate and should be documented in the code and

documents submitted. For example, type of triangle …

Create a command line driven menu that allows a user to construct each of the TwoDimensional and

ThreeDimensional Shape subclasses. The menu should continue to loop prompting for a specific class

and then prompt for appropriate input parameters. The values returned should be the volume or area

as appropriate to the shape. Error checks should be in developed to make sure appropriate menu items

and types of data were input and prompt the user to enter to correct data. An option to exit the

program should be available as well that will provide an appropriate Thank you message along with the

current date and time.

The following represents a possible menu session for a user:

*********Welcome to the Java OO Shapes Program **********

Select from the menu below:

1. Construct a Circle

2. Construct a Rectangle

3. Construct a Square

4. Construct a Triangle

5. Construct a Sphere

6. Construct a Cube

7. Construct a Cone

8. Construct a Cylinder

9. Construct a Torus

10. Exit the program

2

You have selected a Rectangle

What is the length?

4

What is the Width?

9.5

The area of the Rectangle is 38.

Would you like to continue? (Y or N)

3

Sorry I do not understand. Enter Y or N

Y

Select from the menu below:
1. Construct a Circle
2. Construct a Rectangle
3. Construct a Square
4. Construct a Triangle
5. Construct a Sphere
6. Construct a Cube
7. Construct a Cone
8. Construct a Cylinder
9. Construct a Torus
10. Exit the program

Thanks for using the program. Today is Nov 11 at 1:40 PM.

Submission Requirements:

1. Submit all of your Java source files (each class should be in a separate .java file). These files

should be zipped and submitted with the documentation.

2. UML class diagram showing the type of the class relationships.

3. Developer’s guide describing how to compile and execute the program. The guide should

include a comprehensive test plan that includes evidence of testing each component of the

menu with screen captures and descriptions supporting each test. Documentation includes

Lessons learned.

Your compressed zip file should be submitted to the Project 1 folder in LEO no later than the due

date listed in the classroom calendar.
