[java] Creating multiple objects with different names in a loop to store in an array list

I am trying to create mutliple objects of a type of class I made. I then want to transfer these values into the array list. How can I create objects using a while loop that have different names. For example here is my code now, but it would only make an object of one name.

Customer cust = new Customer("bob", 20.0);

and my constructor if you want to see:

public Customer(String customerName, double amount)
{
    String name=customerName;
    double sale=amount;
}

StoreTest class (with main method):

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

public class StoreTest {

ArrayList<Customer> store = new ArrayList<Customer>();

public static void main (String[] args)
{
        double sale=1.0; //so the loop goes the first time
        //switch to dowhile
        Scanner input = new Scanner(System.in);

        System.out.println("If at anytime you wish to exit" +
                ", please press 0 when asked to give " +
                "sale amount.");
        while(sale!=0)
        {
            System.out.println("Please enter the " +
                    "customer's name.");
            String theirName = input.nextLine();

            System.out.println("Please enter the " +
                    "the amount of the sale.");
            double theirSale = input.nextDouble();

            store.addSale(theirName, theirSale);
        }
        store.nameOfBestCustomer();
}

}

Customer class:

public class Customer {

private String name;
private double sale;

public Customer()
{

}

public Customer(String customerName, double amount)
{
    name=customerName;
    sale=amount;
}
}

Store class (has methods for messing with arraylist:

import java.util.ArrayList;


public class Store {

//creates Customer object and adds it to the array list
public void addSale(String customerName, double amount)
{
    this.add(new Customer(customerName, amount));
}

//displays name of the customer with the highest sale
public String nameOfBestCustomer()
{
    for(int i=0; i<this.size(); i++)
    {

    }
}
}

You can use this code...

public class Main {

    public static void main(String args[]) {
        String[] names = {"First", "Second", "Third"};//You Can Add More Names
        double[] amount = {20.0, 30.0, 40.0};//You Can Add More Amount
        List<Customer> customers = new ArrayList<Customer>();
        int i = 0;
        while (i < names.length) {
            customers.add(new Customer(names[i], amount[i]));
            i++;
        }
    }
}
