4.5 Design a class as well as a program that creates an
object and calls methods
CSC105 Graded Project 4
READING ASSIGNMENT
Your project must be submitted as a zipped/compressed (*.zip) file that includes
the following files:
Text files (*.txt) of the following:
Your class
Your program’s pseudocode
Screenshot(s) in JPEG format (*.jpg) of the following:
Your flowchart
The results of calling the accelerate method
The results of calling the brake method
A Rich Text Format (*.rtf) or Microsoft Word (*.doc) file that lists the
following information:
Your name
Your student ID number
The exam number
Your email address
For information on how to take and save a screenshot on your computer or to zip
files, review the instructions for CSC105 Graded Project 1. Save your
compressed file as [Your Name]_CSC105_GradedProject4. Your project will
be individually graded by your instructor and therefore may take up to five to
seven days to grade. To submit your graded project, follow these steps:
Log into your student portal.
Click Take Exam next to the lesson you’re working on.
Find the exam number for your project at the top of the Project Upload
page.
Follow the instructions provided to complete your exam.
Be sure to keep a backup copy of any files you submit to the school!

Introduction
You’ll apply the concepts of Lesson 4 to design a class as well as a
program that creates an object and calls methods.
Instructions
Part 1: Design a Class
You’ll design a class named Car that has the following fields:
yearModel—An Integer that holds the car’s model year
make—A String that holds the make of the car
speed—An Integer that holds the car’s current speed
The class should have the following constructor and other methods:
The constructor should accept the car’s model year and make as
arguments. These values should be assigned to the object’s
yearModel and make fields. The constructor should also assign 0
to the speed field.
Design appropriate accessor methods to get the values stored in an
object’s yearModel, make, and speed fields.
The accelerate method should add 5 to the speed field each time
it’s called.
The brake method should subtract 5 from the speed field each time
it’s called.
Create your class in a plain-text editor such as Notepad or TextEdit and

save as a text file (*.txt).
Part 2: Design a Program
You’ll create both pseudocode and a flowchart to design a program that
creates a Car object and then calls the accelerate method five times.
Review Appendices B and C in your textbook for guidance when
working on your project. Use free trials of any of the programs listed in
CSC105 Graded Project 1 to create the flowchart. Write your
pseudocode in a plain-text editor such as Notepad or TextEdit and save
as a text file (*.txt). Also, save a screenshot of your flowchart as a JPEG
file (*.jpg).
After each call to the accelerate method, get the current speed of the
car and display it. Take a screenshot of the results after your fifth time
calling the method, and save it as a JPEG file (*.jpg).
Then, call the brake method five times. After each call to the brake
method, get the current speed of the car and display it. Take a
screenshot of the results after your fifth time calling the method, and
save it as a JPEG file (*.jpg).
Grading Criteria
Your instructor will use the following guidelines to grade your project.
The class contains the required fields and methods. 25
points
