    This is poor advice. You should not allow objects to be in an invalid state. That's what the constructor is for. If you need complex logic then use the factory pattern. Commented Aug 4, 2015 at 9:42

    Constructors are there to establish the class invariants, the sample code doesn't help to assert that at all. Commented Aug 4, 2015 at 9:44
  • @Alex I think base of this idea might be true. imagine an initial sate that needs to be transferred to other state in order to be transferable to other states. although this might be a logical mistake by developer to integrate some operations. Commented Mar 31, 2022 at 12:32
