Notice at top and bottom of page

Hi. I am using Version 4.1.
I am completely new to WordPress and I have run into an error. When I add my header and footer into my wordpress, I get these errors:

( ! ) Notice: Theme without header.php is deprecated since version 3.0 with no alternative available. Please include a header.php template in your theme. in C:\wamp\www\wordpress\wp-includes\functions.php on line 3437

and:

( ! ) Notice: Theme without footer.php is deprecated since version 3.0 with no alternative available. Please include a footer.php template in your theme. in C:\wamp\www\wordpress\wp-includes\functions.php on line 3437

this is the code i am using:
`
get_header( );

if (have_posts()) :
while (have_posts()) : the_post(); ?>

<h2>“><?php the_title(); ?></h2>
<?php the_content(); ?>

<?php endwhile;

else :
echo ‘<p>No content found</p>’;

endif;

get_footer( );

?>
