use Magento\Indexer\Model\Indexer\Collection;

class Index extends \Magento\Framework\App\Action\Action

    /**
     * @var Collection
     */

     * @param IndexerFactory $indexFactory
     * @param Collection $indexCollection
     */

        \Magento\Framework\App\Action\Context $context,
        IndexerFactory $indexFactory,
        Collection $indexCollection
    ) {
        $this->indexCollection = $indexCollection;
        $this->indexFactory = $indexFactory;
        parent::__construct($context);
    }

    public function execute()
    {
        $indexes = $this->indexCollection->getAllIds();
        foreach ($indexes as $index){
            $indexFactory = $this->indexFactory->create()->load($index);
            $indexFactory->reindexAll($index);
            $indexFactory->reindexRow($index); 
        }
    }
}
