Java: Object Responsibility
Answer
Constructor validation ensures objects are created in a valid state.
Including validation within a constructor prevents the creation of objects in an invalid state. For instance, a `User` object should validate that an email is well-formed during construction, ensuring all `User` instances are consistent and reliable from the moment they are created.
