CMSC 335 Project 3

Overview

In this project you will construct a Java Swing GUI that uses event handlers, listeners and incorporates

Java’s concurrency functionality and the use of threads. The following book may be useful to help you

become comfortable with Thread processes.

https://learning.oreilly.com/library/view/java-7-concurrency/9781849687881/index.html

You should focus on the first 4 chapters.

If you have not previously requested a Safari account follow the details on this page to sign-up for your Safari Account:

You'll need to sign in using your UMGC student email account. Once you sign in, you'll have immediate access to the content, and you'll shortly receive an e-mail from Safari prompting you to set up a password and complete your account creation (recommended).

Students: Your UMUC e-mail account is your username + @student.umuc.edu (example: [email protected]).

In addition, a zip file is included that includes several Oracle Java files that use different types of Swing

components as well as threads. I recommend going through the reading and the examples to become

familiar before attempting the final project.

Assignment Details

As a new engineer for a traffic congestion mitigation company, you have been tasked with developing a

Java Swing GUI that displays time, traffic signals and other information for traffic analysts. The final GUI

design is up to you but should include viewing ports/panels to display the following components of the

simulation:

1. Current time stamps in 1 second intervals

2. Real-time Traffic light display for three major intersections

3. X, Y positions and speed of up to 3 cars as they traverse each of the 3 intersections

Some of the details of the simulation are up to you but the following guidelines will set the guardrails:

1. The components listed above should run in separate threads.

2. Loop through the simulation with button(s) providing the ability to start, pause, stop and

continue the simulation.

3. You will need to use basic distance formulas such as distance = Speed * time. Be sure to be

consistent and define your units of measure (e.g. mile/hour, versus km/hour)

4. Assume a straight distance between each traffic light of 1000 meters.

5. Since you are traveling a straight line, you can assume Y = 0 for your X,Y positions.

6. Provide the ability to add more cars and intersections to the simulation through the GUI.

7. Don’t worry about physics. Assume cars will stop on a dime for red lights, and continue through

yellow lights and green lights.

8. Document all assumptions and limitations of your simulation.

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 3 folder in LEO no later than the due

date listed in the classroom calendar.
