How to get the address / url / uri of a file from a File entity in drupal?

$file = \Drupal\file\Entity\File::load(123); /** @var \Drupal\file\FileInterface $file */
$file_relative_url = $file->createFileUrl(); // /sites/default/files/example.jpg
$file_absolute_url = $file->createFileUrl(FALSE); // http://example.com/sites/default/files/example.jpg
$file_uri = $file->getFileUri(); // public://example.jpg
