Lab 6a: Tracking Sales
Lab 6a: Tracking Sales
File Sales6a.java contains a Java program that prompts for and reads in the sales for each of 5 salespeople in a company. It then
prints out the id and amount of sales for each salesperson and the total sales. Study the code, then compile and run the program to
see how it works. Now modify the program as follows:
1.
Find the average - Compute and print the average sale per person. (You can compute this directly from the total; no loop is
necessary.)
Find maximum sale –
a. Find Max sale and associate id - Find the associate who had the maximum sale and the value of that sale
b. Print Max sale and associate id - Print both the id of the salesperson with the max sale and the amount of the sale,
e.g., "Salesperson 3 had the highest sale with $4500." Note that you don't need another loop for this; you can do it
in the same loop where the values are read and the sum is computed.
Find minimum sale - Do the same for the minimum sale.
Sales goal - After the list, sum, average, max and min have been printed,
a. Input a sales goal - Ask the user to enter a sales goal.
b. Print ID and $$ of those that exceeded the goal - Then print the id of each salesperson who exceeded that
amount, and the amount of their sales.
c. Print total # of people who exceeded the goal - Print the total number of salespeople whose sales exceeded the
value entered.
No Salesperson with Zero for an ID - The salespeople are objecting to having an id of 0—no one wants that designation.
Modify your program so that the ids run from 1–5 instead of 0–4. Do not modify the array—just make the information for
salesperson 1 resides in array location 0, and so on.
Allow user to determine how many salespeople there will be - Instead of always reading in 5 sales amounts, at the
beginning ask the user for the number of sales people and then create an array that is just the right size. The program can
then proceed as before.
