Do any of you call setters within constructors?

That is up to you i believe, whether to use a setter or directly assign value, or even implement some logic in constructor for invalid data check, but i'll try to give an example in which you would want to use setters in constructor. So lets say u have a field which can have a ton of invalid states, like a String representing an email for example, and u need to implement a complicated logic to check whether the value passed is valid or not, and also u need that value to be changable (have a setter), after creation of an object. So u implement that logic in a setter, and u have a choice here to implement the same logic for the field in a constructor, or to just call a setter, i think u see which one is better easier etc.
