Class problem

[Deagel]

I have two classes. The first is basically a notebook. The second is an array where im supposed to generate notebooks. Ive written a script generating notebooks but it doesnt work because the first class is not recognized

notebookPile[0] = new NoteBook("Note Book" + Integer.toString(i));

it returns saying cannot find symbol - constructor NoteBook

How do I make it recognise the class.

Code:

class NoteBook {
    String name;

    public NoteBook() {
        this(null);  // or you could do: this("");
    }

    // Java is looking for a constructor that has
    // this signature and cannot find one in the
    // NoteBook class.
    public NoteBook(String s) {
        name = s;
    }
}
