Thread: Array List and Method

For my homework, I had to write a program that prompts the cashier to enter all prices and names, adds them to two arrays lists, calls the method that I implemented, and displays the result and use 0 as the sentinel value. I am having difficulty coming up with a for loop in the method, I believe I have the condition right but I am having trouble with the statements. I now know that String does not have the get property, but I have only done examples with integers and I am not very good with for loops and wouldn't know how to fix it. Any help would be greatly appreciated! Thanks.

public static void main(String[] args) {
   Scanner in = new Scanner(System.in);
   ArrayList<Double> sales = new ArrayList<Double>();
   ArrayList<String> names = new ArrayList<String>();
   System.out.print("Enter Number of Customers");
   double salesAmount;
   System.out.print("Enter Sales for First Customers");
   salesAmount = in.nextDouble();
   while(salesAmount != 0)
   {
       sales.add(salesAmount);
       System.out.println("Enter Name of Customer: ");
       names.add(in.next());
       System.out.println("Enter the next sales amount, 0 to exit: ");
       salesAmount = in.nextDouble();
   }
 
   String bestCustomer = nameOfBestCustomer(sales, names);
 
}
 
public static String nameOfBestCustomer(ArrayList<Double> sales, ArrayList<String> customers)
{
    String name = "";
    double maxSales;
 
    for (int i = 0; i < sales.size(); i++)
    {
        sales.size(name.get); <== it keeps saying "cannot find the symbol variable get"
    }
 return name;
}

I am having difficulty coming up with a for loop in the method,

What is the for loop supposed to do? Normally for loops are used when the number of times to loop is known.

cannot find the symbol variable get

If get is a method, then you need ()s after it, otherwise it is considered a field.

Please edit your post and wrap your code with code tags:

to get highlighting and preserve formatting.

Ok, what have you tried? What steps must the code take to solve that problem?

return the name of the customer with the largest sale. Then we have to return the name of the customer with the largest sale

Is that a repeat?

What are the steps the code must take as it goes through the items in the ArrayList to find the desired value?

It sounds like there are separate parts to the problem.
1) get the data
2) find the desired value
