        // Find the length of bookName
        int bookNameLength = bookName.____();
        
        // Find the length of the String and save it
        ____ authorNameLength = "Terry Pratchett".____;
        
        System.out.println("The length of the book title is " + bookNameLength);
        System.out.println("The length of the author's name is " + authorNameLength);
