Business P7.12 A supermarket wants to reward its best customer of each day, showing the customers name on a screen in the supermarket. For that purpose, the store keeps an ArrayList. In the Store class, implement methods public void addSale(String customerName, double amount) public String nameOfBestCustomer() to record the sale and return 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 a Store object, and displays the best customers name. Use a price of 0 as a sentinel.
