Where should calls to validate a Java object be made; 1) at the end of the constructor, or 2) after the call to new X()? If made in the constructor, then is gets called not only for each new, but if there is a subclass of that object. Your thoughts would be helpful.

It completely depends on the use case and logic. I prefer to call it after new X() as object will have data after some setters are called.

X obj = new X();
obj.setName("xyz");
obj.setId(1);
validator.validate(obj);
