Creating Object in a thread safety way

Question

I think that the following example illustrate what authors wanted to say:

public clsss MyClass {
    public MyClass(List list) {
        // some stuff 

        list.add(this); // self registration

        // other stuff 
    }
}

The MyClass registers itself in list that can be used by other thread. But it runs "other stuff" after the registration. This means that if other thread starts using the object before it finished its constructor the object is probably not fully created yet.
