Wordpress: Display media files on a page based on logged in user

Question

I have a code that displays entire media library files on a page. I want to achieve functionality to display the media files only to users who are currently logged in and the files they have uploaded. If the user did not upload the file it should simply say no file uploaded.

Current PHP snippet:

<?php 
class list_media {
    public function list_media_controller( $atts, $content = "" ) {
        //Get the Shortcode attributes
        extract( 
            shortcode_atts( 
                array( 
                'order' => 'ASC',
                'posts_per_page' => -1,
                'post_status' => null,
                'post_parent' => null,
                'default_styles' => true,
                'date_format' => "Y/m/d"
                ), $atts 
            )
        );

        //Query ARGS
        $args = array(
         'post_type' => 'attachment',
        'author' => $user_ID,
            'posts_per_page' => $posts_per_page,
            'numberposts' => $numberposts,
            'post_type' => 'attachment',
            'post_status' => $post_status,
            'post_parent' => $post_parent, 
            'orderby' => $order_by,
            'order' => $order   
        );

        //Print the first part of the Table
        echo "
        <table class='list_media'>
            <thead>
                <tr>
                    <th class='header'>File</th>

    if( is_user_logged_in() ) {

    //get the currenly logged in user
    $user_ID = get_current_user_id();
    }
        //Get the Media files
       //$attachments = get_posts( $args );
           $attachments = new WP_Query( $args );
        if ( !empty( $attachments ) ) {
            foreach ( $attachments as $attachment ) {
                $attachment_id = $attachment->ID;
                $attachment_title = get_the_title( $attachment_id );
                $attachment_url = wp_get_attachment_url( $attachment_id );
                $attachment_author_id = $attachment->post_author;
                $attachment_author_url = get_author_posts_url( $attachment_id );
                $attachment_author_name = get_the_author_meta( "user_nicename", $attachment_author_id ); 
                $attachment_publish_date = get_the_date( $date_format, $attachment_id );

                $attachment_post_parent_id = $attachment->post_parent;

                if ( !empty( $attachment_post_parent_id ) ) {
                    $attachment_post_parent_title = get_the_title( $attachment_post_parent_id );
                    $attachment_post_parent_url = get_permalink( $attachment_post_parent_id );
                } else {
                    $attachment_post_parent_url = "#!";
                    $attachment_post_parent_title = "Unattached";
                }

                echo "
                <tr>

                    </td>
                    <td class='date'>
                        $attachment_publish_date
                    </td>
                </tr>
                ";
            }
        }

        //Print end of the Table
        echo "
            </tbody>
        </table>
        ";
    }
}
add_shortcode( 'list_media', array( 'list_media', 'list_media_controller') );

?>

After playing with the code i was able to get it right finally. Adding the answer here. I am sure it will help others.

class list_media {
    public function list_media_controller( $atts, $content = "" ) {
        //Get the Shortcode attributes
        extract( 
            shortcode_atts( 
                array( 
                'order' => 'ASC',

                'date_format' => "Y/m/d"

            )
        );
