Conclusion

Always create complete objects. Make their essence immutable to endure through time. Every object needs its essence to be a valid one since inception.

Writing a class without its contract would be similar to producing an engineering component (electrical circuit, VLSI (Very Large Scale Integration) chip, bridge, engine…) without a spec. No professional engineer would even consider the idea.
