Please improve the following code according to the question

This code prints the best customer, please improve it so it prints the top customers according to the question : (JAVA)

public static void main(String[] args) { //The input varuables: String CustomerName; double CustomerSales; ArrayList customers = new ArrayList(); //array list for customers' names ArrayList sales = new ArrayList(); //array list for customers' sales

Scanner in = new Scanner(System.in); //A scanner object

// this will be repeated until the user enters zero while (true) {

//prompt user to enter sales System.out.print("Enter Customer's sales: "); //save user's input into this variable CustomerSales = Float.parseFloat(in.nextLine());

if (CustomerSales == 0) { break; } //add users input to the array list sales.add(CustomerSales);

//prompt user to enter customer's name System.out.print("Enter customer's name: "); //Store the input CustomerName = in.nextLine(); //Add the input to the array list customers.add(CustomerName); } String Answer = nameOfBestCustomer(sales, customers); //ensure that the information exist or print a message telling that there is an error if(Answer.isEmpty()) { System.out.println("No information found"); }else { System.out.println("Best customer is: "+Answer); } }

public static String nameOfBestCustomer(ArrayList sales, ArrayList customers) { String FinalResult = ""; //this will execute if the information are valid if (sales.size() > 0) {

double largest = sales.get(0); FinalResult = customers.get(0);

//get the largest sale value and match it with the name for (int i = 1; i

if (sales.get(i) > largest) { largest = sales.get(i); //result store best customer name FinalResult = customers.get(i); } } } return FinalResult; //return best customer }

}

Improve the program from Part 1 so that it displays the top customers, that is, the top customers with the largest sales, where topN is a value that the user of the program supplies. Implement a method public static ArrayList nameOfBestCustomers (ArrayList sales, ArrayList customers, int topN) If there were fewer than topN customers, include all of them
