Hello Im fresh I need help with the following question Pleas

Hello, I\'m fresh. I need help with the following question. Please use basic Java Code.

Thanks!

A supermarket wants to reward its best customer of each day, showing the customer\'s name on ascreen in the supermarket. For that purpose, the customer\'s purchase amount is stored in anArrayList<Double> and the customer\'s name is stored in a corresponding ArrayList<String>.
Implement a method
public static String nameOfBestCustomer(ArrayList<Double> sales,ArrayList<String> customers)
that returns the name of the customer with the largest sale.
Write a program that prompts the cashier to enter all prices and names, adds them to two array lists,calls the method that you implemented, and displays the result. Use a price of 0 as a sentinel.

====================================================================

Sample output:
Please enter the customer’s name (enter DONE to quit) : Joe   

Please enter Joe’s spending       : 200

Please enter the customer’s name (enter DONE to quit) : Harry

Please enter Harry spending       : 300

.
.
Please enter the customer’s name    : DONE      

Eric has spent the most amount today with a sale of $300

Solution

SuperMarketTest.java

import java.util.ArrayList;
import java.util.Scanner;

public class SuperMarketTest {

  
   public static void main(String[] args) {
       Scanner scan = new Scanner(System.in);
       ArrayList<Double> sales = new ArrayList<Double>();
       ArrayList<String> customers = new ArrayList<String>();
       while(true){
           System.out.print(\"Please enter the customer’s name (enter DONE to quit): \");
           String name =scan.nextLine();
           System.out.print(\"Please enter \"+name+\"’s spending: \");
           double price = scan.nextDouble();
           scan.nextLine();
           if(price == 0){
               break;
           }
           sales.add(price);
           customers.add(name);
       }
       String customerName = nameOfBestCustomer(sales, customers);
       System.out.println(\"Best customer is \"+customerName);
   }
   public static String nameOfBestCustomer(ArrayList<Double> sales, ArrayList<String> customers){
           double max = 0;
           int maxIndex = 0;
           for(int i=0; i<sales.size(); i++){
               if(max < sales.get(i)){
                   max = sales.get(i);
                   maxIndex = i;
               }
           }
           return customers.get(maxIndex);
   }
}

Output:
