Question

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 show the user’s input of each pair of product number and quantity, the calculated line cost for that product, and the cumulative order cost so far. Then, after the sentinel value is input your program must display the total retail cost for the full order.

You must show all 11 user inputs (5 product number and quantity pairs and the sentinel value) and all the corresponding program outputs, not just a subset of the inputs and outputs.
