Question

Using Java language (in program NetBeans).

1) Using a 2 dimensional array

Your company has 4 grocery stores. Each store has 3 departments where product presentation affects sales (produce, meat, frozen). Every so often a department in a store gets a bonus for doing a really good job.

You need to create a program that keeps a table of bonuses in the system for departments. Create a program that has a two dimensional array for these bonuses. The stores can be the rows and the departments can be the columns. Have the program ask the user three times for a bonus amount, grocery store number (1-4), and department number (1-3) and add the bonus amount to the appropriate place in the array based on the numbers they gave. After this is done, add up the bonuses for each of the 4 stores [the 4 rows in your 2 dimensional array] and display them for the user.
