You can show your error/success message with ManagerInterface. Here is an example to show you how you can use it.


    use Magento\Backend\App\Action\Context;
    use \Magento\Framework\Controller\ResultFactory;

class ClassName extends \Magento\Framework\App\Action\Action

    protected $_messageManager;

    public function __construct(
        Context $context,
        \Magento\Framework\Message\ManagerInterface $messageManager
    ) {
        $this->_messageManager = $messageManager;

    public function execute()
        // Do Validation
        if (empty($input)) {
            $this->_messageManager->addErrorMessage('Your Error Message');
        } else {
            $this->_messageManager->addSuccessMessage('Your Success Message');
        $resultRedirect = $this->resultFactory->create(ResultFactory::TYPE_REDIRECT);

        return $resultRedirect;
