Answer:
import java.util.Scanner;
public class Sales
{
 public static void main(String[] args) {
    	
    	int sum;
    	Scanner input = new Scanner(System.in);
    	
    	System.out.print("Enter number of salespeople: ");
    	int salespeople = input.nextInt();
    	int[] sales = new int[salespeople];
         
    	for (int i=0; i<sales.length; i++)
     {
      System.out.print("Enter sales for salesperson " + (i+1) + ": ");
      sales[i] = input.nextInt();
     }
    	System.out.println("\nSalesperson   Sales");
    	System.out.println("--------------------");
    	sum = 0;
        int maxSale = sales[0];
        int minSale  = sales[0];
        int minId=1; 
        int maxId=1;
     for (int i=0; i<sales.length; i++)
     {
                System.out.println("     " + (i+1) + "         " + sales[i]);
  sum += sales[i];
   if(maxSale < sales[i])
            {
                maxSale = sales[i];
                maxId = i+1;
            }
            if(minSale > sales[i])
            {
                minSale = sales[i];
                minId = i+1;
            }
    }
 System.out.println("Total sales: " + sum);
        System.out.println("The average sale is: " + sum / salespeople );
        System.out.println("Salesperson "+ maxId + " had the highest sale with "+ maxSale + ".");
        System.out.println("Salesperson "+ minId + " had the lowest sale with "+ minSale + ".");
        
        int amount = 0;
        int counter = 0;
        System.out.print("Enter an amount: ");
        amount = input.nextInt();
        for (int i=0; i<sales.length; i++)
     {
      if(sales[i] > amount) {
          counter++;
          System.out.println("Salesperson "+ (i+1) + " exceeded given amount. (Number of sales: " + sales[i] +")");
      }
     }
        System.out.println("Number of salespeople exceeded given amount is: "+ counter);
 }
}
Explanation:
- Ask the user for the number of salesperson
- According to entered number, create an array called sales to hold sale number for each person
- In the first for loop, assign the given sales numbers
-  In the second for loop, print all the sales people with sales, calculate the total sales. Also, find the minimum and maximum sales numbers with associated individuals. 
- Print total, average, highest, and lowest sales.
- Ask user enter an amount
- In the third for loop, find the sales people who exceeded this amount. 
- Print number of sales people who exceeded the amount.
