    Default Array List; How to pass objects into another arraylist

    I'm supposed to compare objects within a list to a given value and then pass them to another list if the values tally. But the code does not compile; javac says cannot find symbol

    public class Librarian {
    private ArrayList<Book> bookList;

    public Librarian () {
    bookList = new ArrayList<Book>();
    }

    public ArrayList<Book> findBooksWrittenBy(ArrayList<Book> inputList, String author) {
    ArrayList<Book> authorList = new ArrayList<Book>();

    for (int position = 0 ; position < inputList.size() ; position++ ) {
    Book temp = inputList.get(position);
    String bkAuthor = temp.getAuthor();
    if (bkAuthor.equalsIgnoreCase(author)) {
    authorList.add(temp);
    }
    }
    return authorList;
    }


    }

    1. Enclose the code in the code tags.
    2. Format code properly, use some editor.
    3. Is this your whole code?????
    If yes, i will recommend you to read tutorials. If no, i will suggest to read forum rules.

    Thanks
