Question

CSC

MUST BE IN JAVA

Design a program as per the following information using the accompanying data file.

Here is the datafile: sodaSalesB.dat

Make sure the program compiles and that you include pseudo code. The assignment

is worth 100 points.  (Lack of pseudo code will cost you 15pts)

You have been asked to produce the report below. This report will tell the company how sales are going. You will read the file named sodasales.dat The values are the brand name, number sold, the cost per bottle, the retail price.

                           Soda Sales

   

                Bottles   Cost     Retail     Profit     

   Soda     Sold      Bottle   Bottle     Brand     

   -----    ----      -----    -------    -------     

You will produce a summary line at the end of the report. The summary section should display the average cost, the average price, the highest and the lowest priced soda. You will also display total profit.

You will give the user the choice of either sending the report to the screen, file, or both.

   Remember profit is the profit per bottle multiplied by the number of bottles sold.

I have given you two files the A file has a stock ID (int) for the brand the second uses a name (String).

INFORMATION FOR ABOVE PROGRAM:

Coke 34 3.00 5.00

Sprite 18 2.89 4.30

Fanta Mango 21 3.35 5.99

Orange Crush 35 4.00 6.00

Browns Cream Soda 43 4.25 5.75

The data file is added below already
