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 {

You need `items.get(o)` instead of `items(0)` and `.length` instead of `.size()`, and `order.write(Double.toString(baseTotal));` — Codebender, Jul 16 '15 at 17:03
I refer you to [the `List` API](https://docs.oracle.com/javase/8/docs/api/java/util/List.html) and [the `PrintWriter` API.](https://docs.oracle.com/javase/8/docs/api/java/io/PrintWriter.html) For future reference, if you're curious on how to invoke a specific function using a specific class, that should be your first port-of-call. — Makoto, Jul 16 '15 at 17:04

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));

This only answers half of the question. What about those `PrintWriter` calls? – Makoto Jul 16 '15 at 17:04

I did add to them in a different method but didn't want to put all that code up there. – David Jul 16 '15 at 17:10

String name = items.get(0); //ERROR APPEARS HERE
String service = items.get(1); //ERROR APPEARS HERE
int zipcode = quantities.get(0); //ERROR APPEARS HERE
double servicePrice = prices.get(0); //ERROR APPEARS HERE

ArrayList#get(int) to get a value from list object

productName[y] = items.get(i); //ERROR APPEARS HERE
productPrice[y] = prices.get(i); //ERROR APPEARS HERE
productQuantity[y] = quantities.get(i); //ERROR APPEARS HERE

for(int i = 0; i < productPrice.length; i++) {
  //ERROR APPEARS HERE but points at .size()
     productTotal[i] = productPrice[i] * productQuantity[i];
  }

 for(int i = 0; i < productTotal.length; i++) {
 ......................

productPrice and productPrice are arrays. so use length to check length of array.

PrinerWriter#write(String) not double

    order.write(""+baseTotal);
    order.write(""+taxTotal);
    order.write(""+grandTotal);
    //All three .write() statements return error

This only answers half of the question. What of the calls to the `PrintWriter`? — Makoto, Jul 16 '15 at 17:06
