Project #76461 - Musical instrument program (Java)

Homework 3b

Before attempting this project, be sure you have completed all of the reading assignments, hands-on labs, discussions, and assignments to date.

(25 points) Create your own Java class that represents your favorite musical instrument. Your musical instrument class should have at least 3 constants, 5 private data fields, getters and setters for each private data field, a toString() method, and three additional methods of your choice. Create a test class that constructs at least 5 of your musical instrument 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. You can pick any instrument you want. When designing your class, think about what would make sense to describe and use the instrument. For example, if you selected a trumpet, you might need to provide the number of valves, the manufacturer, if the instrument is using a mute, the volume or even notes the trumpet is playing. Make this your own creation and have fun with it.

Submission requirements:

 

Your deliverables include your Java files (.java) and a single word document. The Java files should be named appropriately for your applications. Your word document should include screen shots showing the successful compiling and running of each application, and a detailed description of the test plan for each application. The screen shots should document your successful use of the IDE. The test plan should include the input, expected output, actual output and if the test case passed or failed. Submit your files to the Homework 3b assignment area no later than the due date listed in the calendar.
