ITS 320 Assignment 3 Decision Control and Loops with User Interaction
1) Write a Java application that prompts the user for pairs of inputs of a product number (1-5), and then an integer quantity of units sold (this is two separate prompts for input values). You must use a switch statement and a sentinel – controlled loop (i.e. a loop that stops execution when an out of range value, such as -1, is input). All 15 items below are for a single purchase. There are five sets of inputs as follows:
Product 1 1 unit (cost is $2.98 per unit)
Product 2 2 units (cost is $4.50 per unit)
Product 3 3 units (cost is $9.98 per unit
Product 4 4 units (cost is $4.49 per unit)
Product 5 5 units (cost is $6.87 per unit)
Your application must calculate and display the total retail value of all products sold, after all 5 pairs of inputs are completed. You must also display the total after each new pair of input values is entered. (This program was taken from Exercise 5.17 on page 228 of Deitel & Deitel’s “Java How to Program (Sixth Edition)” (2005 by Pearson Publishing Co.))
2) You may use the Windows Command Prompt command line interface or any Java IDE you choose to compile and execute your program.
3) You are to submit the following deliverables to the Assignment Dropbox in a single Microsoft Word file:
A screen snapshot of your Java source code (just the beginning is OK) as it appears in your IDE (e.g. jGRASP, Net Beans, Eclipse, etc.) or editor (e.g. a Windows Command Prompt DOS “more” of the .java file’s first screen).
A listing of your entire Java source code in the same Microsoft Word file as item a), and following item a). You can simply copy and paste the text from your IDE into Word. Be sure to maintain proper code alignment by using Courier font for this item.
A screen snapshot of your program’s input and output in the same Microsoft Word file, and following item b). You must include screen snapshots of all inputs and all outputs,not just a sample.
4) Your instructor may compile and run your program to verify that it compiles and executes properly.
5) You will be evaluated on (in order of importance):
Inclusion of all deliverables in Step #3.
Correct execution of your program.
Adequate commenting of your code.
Good programming style (as specified in the textbook’s examples).
Neatness in packaging and labeling of your deliverables
