Java ArrayList names "Cannot Find Symbol" and "No Suitable Method" for PrintWriter

Question

After looking around, I haven't been able to find either of these questions answered elsewhere. If they have been and I couldn't find them, please point me in the right direction.

I use three ArrayLists in my program to store a customer's order information. When I try to call them, I get a "cannot find symbol" error for the variable names of each ArrayList.

At the end of the method, I try to write the bill amounts to the file and it returns "no suitable method found" error.

Error locations are noted a comments and a copy of the error messages is at the end.

     else {
     //if order cancelled, return cancellation to calling method

Answer 1

You should be using the ArrayList get method to access the element of an array.`

String name = items.get(0);          
String service = items.get(1);

It also looks like that you don't add anything to the ArrayLists in this code.

As for the second error, you are not allowed to write a double. Try converting the double to a String and then writing it.

order.write(String.valueOf(baseTotal));
