Answer 1

I have not read this anywhere but its my experience. When you call new D(), the constructor chain begins, it first creates an java.lang.Object and then extends it to an A, I mean after creating the Object (which is root of all objects), A is initialized on it, by adding memory for A's members, including fields and methods (which are a pointer to some code!). And then it extends to B and so on.

In the process of extension if a method is overriden, the method pointer in the object will point to new code.

It will be only one reference to D.
