Homework 3 HeadPhone

Homework 3
Before attempting this project, be sure you have completed all of the reading assignments, hands-on
labs, discussions, and assignments to date.
Create a Java class named HeadPhone to represent a headphone set. The class contains:
 Three constants named LOW, MEDIUM and HIGH with values of 1, 2 and 3 to denote the
headphone volume.
 A private int data field named volume that specifies the volume of the headphone. The
default volume is MEDIUM.
 A private boolean data field named pluggedIn that specifies if the headphone is plugged
in. The default value is false.
 A private String data field named manufacturer that specifies the name of the
manufacturer of the headphones.
 A private Color data field named headPhoneColor that specifies the color of the
headphones.
 A private String data field named headPhoneModel that specifies the Model of the
headphones.
 getter and setter methods for all data fields.
 A no argument constructor that creates a default headphone.
 A method named toString() that returns a string describing the current field values of
the headphones.
 A method named changeVolume(value) that changes the volume of the headphone to
the value passed into the method
Create a TestHeadPhone class that constructs at least 3 HeadPhone objects. For each of the objects
constructed, demonstrate the use of each of the methods. Be sure to use your IDE to accomplish this
assignment.
The google recommended Java style guide, provided as link in the week 2 content, should be used to
format and document your code. Specifically, the following style guide attributes should be addressed:
 Header comments include filename, author, date and brief purpose of the program.
 In-line comments used to describe major functionality of the code.
 Meaningful variable names and prompts applied.
 Class names are written in UpperCamelCase.
 Variable names are written in lowerCamelCase.
 Constant names are in written in All Capitals.
 Braces use K&R style.
Submission requirements
Deliverables include all Java files (.java) and a single word (or PDF) document. The Java files should be
named appropriately for your applications. The word (or PDF) document should include screen captures
showing the successful compiling and running of each of the test cases. Each screen capture should be
properly labeled clearly indicated what the screen capture represents. The test cases table should be
included in your word or PDF document and properly labeled as well.
Submit your files to the Homework 3 assignment area no later than the due date listed in your LEO
classroom. You should include your name and HW3 in your word (or PDF) file submitted (e.g.
firstnamelastnamehw3.docx or firstnamelastnamehw3.pdf)
