Retrieving Blog List, Author, Date of post

GIVEN THIS SET OF CODES HOW CAN I DISPLAY THE AUTHORS NAME AND DATE OF POST ON WORDPRESS? This code curently displayed just the latest blog list but dont have the author and date under the title of the post.

Thanks.

//get post type ==> regular posts
global $post;
$args = array(
‘post_type’ =>’post’,
‘numberposts’ => ‘4’,

);

$blog_posts = get_posts($args);
