How To: What Replaces Mage::throwException($errorMsg); in Magento 2?

if ($errorMsg) 
    {
      Mage::throwException($errorMsg);
    }

and  Mage::getUrl

public function getOrderPlaceRedirectUrl()
  {
    return Mage::getUrl('skypay/payment/redirect', array('_secure' => false));
  }

Try to use like this :

catch (\Exception $e) {
                throw new \Magento\Framework\Exception\LocalizedException(__('%1', $e->getMessage()));
            }

or

if ($errorMsg) 
{
  throw new \Exception($errorMsg);
}

For second code solution :

$this->_url->getUrl('skypay/payment/redirect', ['_secure' => false]);
