调用未定义的方法JController :: getInstance()

i seem to have tried everything. I am trying to learn how to create a new component and currently my folder structure looks like this (please note that the component does install).

This is a picture of my folder structure:

enter image description here

Ive closed some of it because i found it irelevant but please if you need to see whats inside of them please let me know.

as i stated above the component does install without problems. however when i try to access it i get the following error:

Fatal error: Call to undefined method JController::getInstance() in /home/marcrasm/public_html/Joomla/administrator/components/com_helloworld/helloworld.php on line 13

Now the file it is refering to is this one:

defined('_JEXEC') or die ('Restricted access');


$doc = JFactory::getDocument();

// gets the instance of the controller
// Get an instance of the controller prefixed by HelloWorld
$controller = JController::getInstance('HelloWorld');

// Perform the Request task
$input = JFactory::getApplication()->input;

// Redirect if set by the controller

I know it can be hard to tell but does anyone know what the problem might be?

    Please check Joomla version

    In 3.X

       $controller  = JControllerLegacy::getInstance('HelloWorld');

    In 2.X

       $controller = JController::getInstance('HelloWorld');

    The error message says that the JController does not have the static method getInstance().

    You don't say what version you are on but you probably want JControllerLegacy for J3 unless you are building with the new MVC. JController does not have a getInstance() Method but JControllerLegacy does see github.com/joomla/joomla-cms/blob/master/libraries/joomla/controller
