use Joomla\CMS\MVC\Controller\BaseController; class MyController extends BaseController { public function __construct() { parent::__construct(); } }In this example, we are creating a new class called MyController that extends the BaseController class in the Joomla CMS. We then define a constructor method for our new class that simply calls the constructor method of the parent class using the `parent` keyword. This initializes our controller object with the necessary properties and methods needed to handle requests. The package library for this code example is the Joomla CMS, which is a content management system written in PHP. The JController __construct class is part of the MVC (Model-View-Controller) framework of the Joomla CMS.
