 */
abstract class Component {
    protected $type;
    protected $name;
    function __construct($type, $name)
    {
        $this->type = $type;
        $this->name = $name;
    }
    abstract public function add(Component $component);
    public function display()
    {
        printf("print $this->type($this->name)\n");
    }
}

abstract class Container extends Component {
    protected $lists = [];
    public function __construct($type, $name)
    {
        parent::__construct($type, $name);
    }
    public function add(Component $component) :void
    {
        $this->lists[] = $component;
    }
    public function display()
    {
        parent::display();

            $field->display();
        }
    }
