In C++, the lifetime of an object begins when the constructor finishes successfully. Inside the constructor, the object does not exist yet.
Q: What does emitting an exception from a constructor mean?
A: It means that construction has failed, the object never existed, its lifetime never began. [source]
My question is: Does the same hold true for Java? What happens, for example, if I hand this to another object, and then my constructor fails?
Foo()
{
Bar.remember(this);
throw new IllegalStateException();
}
Is this well-defined? Does Bar now have a reference to a non-object?
