Question

File Sales.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. Compute and print the average sale. (You can compute this directly from the total; no loop is necessary.)
2. Find and print the maximum sale. 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.
3. Do the same for the minimum sale.
4. After the list, sum, average, max and min have been printed, ask the user to enter a value. Then print the id of each
salesperson who exceeded that amount, and the amount of their sales. Also print the total number of salespeople whose
sales exceeded the value entered.
5. 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 reside in array
location 0, and so on.
6. 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.

       public static void main(String[] args) {

              Scanner scan = new Scanner(System.in);

              System.out.print("How many salespersons are there? ");

              int[] sales = new int[scan.nextInt()];

              int sum;

              for (int i=0; i<sales.length; i++) {

                     System.out.print("Enter sales for salesperson " + (i+1) + ": ");

                     sales[i] = scan.nextInt();

              }

              System.out.println(" Salesperson Sales");

              int max = 0;

              int min = 0;

                     }

                     sum += sales[i];

              }

              System.out.println(" Total sales: " + sum);

              System.out.println("Average sales: " + sum / 5.00);

              System.out.println("Salesperson " + (max+1) + " had the highest sale with $" + sales[max] + ".");

              System.out.println("Salesperson " + (min+1) + " had the lowest sale with $" + sales[min] + ".");

              System.out.print("Enter a sales amount: ");

              int cutoff = scan.nextInt();

              int total = 0;

              System.out.println(" Salespersons that exceeded the cutoff");

              System.out.println("--------------------");

              for(int i = 0; i < sales.length; ++i) {

                     if(sales[i] > cutoff) {

                           System.out.println(" " + (i+1) + " " + sales[i]);

                           total++;

                     }

              }

              System.out.println(" " + total + " salespersons exceeded the cutoff.");

       }
