Generic = does not conform to bounds of method

[James Brooks]

OK, so generics are killing me here. Sorry for all of the questions, but you don't know until you ask, right? Why do I get the following error if I clearly declare myList to be an array of Strings and bound the method with String?

<T>fillArray(T...) in Ch15.ArrayList<T> cannot be applied to (Ch15.ArrayList<java.lang.String>); inferred type argument(s) Ch15.ArrayList<java.lang.String> do not conform to bounds of type variable(s) T

public class ArrayList<T> {
private T[] list;

   public static void main(String args[]){
       ArrayList<String> myList = new ArrayList<String>(5);
       fillArray(myList);

   }
   public ArrayList(int size){

        list = (T[]) new Object[size];
   }
   public static <T extends String> void fillArray(T ... list){

   }

}

fillArray expects any number of Strings, or a single String[]. You are passing an ArrayList<String>. That does not match, now does it?

Don't you mean

fillArray(myList.list);

Because that does compile (with a warning about the cast to T[]).

OK, so I wasn't passing it the instance variable list[] like I thought I was doing. I see that now, thank you!
