Competency

In this project, you will demonstrate your mastery of the following competency:

• Write programs by applying concepts and principles of object-oriented programming

Scenario

You work for Global Rain, a software engineering company that

specializes in custom software design and development. As a junior

software developer, you are part of a software development team

that collaborates to create solutions for entrepreneurs, businesses,

and government agencies around the world.

As part of a development team at Global Rain, you will be designing

and developing custom software for a local pet boarding and

grooming business, Pet Boarding and Grooming (Pet BAG). Pet BAG

is seeking a way to modernize its operations by introducing custom

software that will help replace inefficient paper-based processes.

Your Global Rain team will collaborate to develop an app that will have the following initial

functional areas: Check-in pets, Check-out pets, Pet management, and Reports.

As part of this team, you have been tasked with completing some preliminary work that consists of

writing a Java class, writing pseudocode, and creating a flowchart. You will provide these

deliverables to your supervisor.

Directions

Pet BAG has provided you with a specification document detailing its software needs and design

documentation from your supervisor to complete your tasks.

1. Before you begin, it is

important to analyze your

client’s software requirements

and the design documentation

from the Supporting Materials

section. Specifically, review the

Pet BAG specification



document and the UML Class

diagram, paying close attention

to the class hierarchy,

attributes, and behaviors.

2. To begin, open the Virtual Lab by clicking on the link in the Virtual Lab Access module. Then

open your integrated development environment (IDE) and create the Pet class based on the

UML Class diagram. The Pet class must meet all the specifications from the class diagram

including the following:

◦ All attributes with appropriate data structures

◦ At least one constructor method

◦ Accessors and mutators for all attributes

3. When you are done implementing the Pet class, refer back to the Pet BAG specification

document and select either the pet check-in or check-out method. These methods are detailed

in the Functionality section of the specification document. You will develop pseudocode and a

flowchart for the method you select.

4. Based on the method you chose, write pseudocode that lays out a plan for the method,

ensuring that you organize each step in a logical manner. Remember, you will not be creating

the actual code for the method, and you do not have to write pseudocode for both methods.

5. Based on the pseudocode you wrote, use the tool of your choice to create a flowchart for the

method you selected. Your flowchart will help your team communicate how you are planning to

develop the software for your client. In your flowchart, be sure to do the following:

◦ Include start and end points.

◦ Include appropriate decision branching.

◦ Align the flowchart to the check-in/check-out process.

6. Based on your software design and development experience, your supervisor has asked you to

articulate your programming approach. This will help ensure clarity, consistency, and efficiency

among all developers working on this app. Specifically, you have been asked to briefly explain

how you applied object-oriented programming principles and concepts (conditional statements,

inheritance, and so on) in the your software development work thus far.

What to Submit

To complete this project, you must submit the following:

Pet.java Class File

As part of your tasks for the software development team, create the Pet class in your integrated

development environment (IDE). To submit this deliverable, save the Pet class file as Pet.java.

Global Rain Summary Report

As a junior software developer, you will use the Global Rain Summary Report Template to complete

the report. Your report must contain your pseudocode, flowchart, and explanation of the object-

oriented programming principles you applied.

Supporting Materials

Use the following resources to support your work on this project:

Pet BAG Specification Document

Review this specification document provided by Pet BAG to understand your client’s software

requirements. You will use these requirements to create your flowchart and write your pseudocode.

UML Class Diagram

Use this UML class diagram, prepared by the senior developer leading your team, to implement the

Pet class. This class diagram demonstrates the Pet class, Dog class, and Cat class and illustrates

inheritance. A text version of this image is also available: UML Class Diagram Text Version.

Downloading Files From Eclipse Tutorial

You will write, test, and run your Pet class file using an integrated development environment (IDE).

Review this tutorial to learn how to save and export files from your IDE. Important: Do not change

the names of any class files.

The following rubric will be used to assess Project One. Familiarize yourself with this document as

you work on the project, and return to this rubric before you submit Project One to make sure

you’ve included everything you need to be successful.
