How to error message in helper class

Hi Team,

I have created trigger for Rolllup summary from child to Parent using helper classes.
How can we show the error message to user, if the parent object is not updated from child object.
Please let me know.

Thanks,
Nandu.

You can use the 
.AddError method 
  
Trigger.new[0].addError('bad');
