PHPStorm highlight error?

Question

PHP

Guys, sorry for the noob question, I'm just studying php, tell me what the error is, phpStorm underlines the error
Maybe I have the wrong path
When you hover over the mouse, the editor shows that the object was not found, include the expression is not allowed

code from all
User.php files

<?php

namespace Models\Users;

class User {
     private $name;

     public function __construct($name)
     {
          $this->name = $name;
     }
     public function getName():string
     {
          return $this->name;
     }
}

Article.php

<?php
namespace Models\Articles;

use Models\Users\User;

class Article {
     private $title;
     private $text;
     private $author;

     public function __construct(string $text, string $title, User $author)
     {
          $this->title = $title;
          $this->text = $text;
          $this->author = $author;
     }
     public function getTitle(): string
     {
          return $this->title;
     }
     public function getText(): string
     {
          return $this->text;
     }
     public function getAuthor(): User
     {

     }
}

storm does not replace your variable with all your classes. That highlights the error about the path not found.
I recommend looking at composer at your leisure, it makes sense to write your own autoloaders only for some very specific tasks.
