Assignment 1

Before attempting this project, be sure you have completed all of the reading assignments,
nongraded exercises, discussions, and assignments to date.
Write a Java program which:
(1) Prompts a user to enter customer id, unit price in this format (e.g. 3.75), quantity (as whole
number), product description, and discount in this format (e.g., .10) (use Scanner for input).
(2) Calculates the customer’s overall order total before and after discount.
(3) Displays the input data along with the order total before and after the discount to the console.
To calculate order total before discount: (unit price multiplied by quantity)
To calculate order total after discount: (unit price multiplied by quantity) multiplied by 1
minus (unit price multiplied by quantity) multiplied by discount
• Example 1: For this example, given unit price of 5.00 with a quantity of 2, and the
discount of .10: (5.00*2) = 10.00 order total before discount and (5.00*2) * 1 –
(5.00*2) * .10 = 9.00 order total after discount
• Example 2: For this example, given unit price of 7.00 with a quantity of 3, and the
discount of .15: (7.00*3) = 21.00 order total before discount and (7.00*3) * 1 –
(7.00*3) * .15 = 17.85 order total after discount
• Example 3: For this example, given unit price of 12.50 with a quantity of 2, and
the discount of .10: (12.50*2) = 25.00 order total before discount and (12.50*2) *
1 – (12.50*2) * .10 = 22.50 order total after discount
Summary of the Examples:

Example # Unit Price Quantity Discount Total Price
(Before
Discount)
Total Price
(After
Discount)
1 5.0 2 .10 10.00 9.00
2 7.0 3 .15 21.00 17.85
3 12.50 2 .10 25.00 22.50

 

Test program:
A minimum of 3 test cases should be supplied in the form of table with columns indicating the
input values, expected output, actual output and if the test case passed or failed. This table should
contain 4 columns with appropriate labels and a row for each test case. An example template is
shown below. Note that the actual output should be the actual results you receive when running
your program and applying the input for the test record.
Make sure your Java program is using the recommended style such as:
• Javadoc comment up front with your name as author, date, and brief purpose of the
program
• Comments for variables and blocks of code to describe major functionality
• Meaningful variable names and prompts
• Class names are written in upper CamelCase
• Constants are written in All Capitals
• Use proper spacing and empty lines to make code human readable
Capture execution:
You should capture and label screen captures associated with compiling your code and running
each of your 3 test cases.
Here is a sample run:
Enter customer id: 4225
Enter unit price in decimal format (e.g. 3.5): 5.0
Enter quantity: 2
Enter product description: Whole Wheat Bread
Enter discount in decimal format (e.g. .05): .10
ORDER DATA:
Customer id: 4225
Unit Price: 5.00
Quantity:2
Product Description: Whole Wheat Bread
Discount: .10
Order total BEFORE discount: 10.00
Order total AFTER discount: 9.0

 

Example test cases:

Test Case 3 To be completed To be completed
Submission requirements
Deliverables include Java program (.java) and a single Word (or PDF) document. The Java and
Word/PDF files should be named appropriately for the assignment (as indicated in the
SubmissionRequirements document.
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 Assignment 1 submission area no later than the due date listed in your online
classroom.
