I got a question:
What exactly does it mean by doing the following?
/*some code*/
/*some code*/
classA xyz = new classB();
/*some code*/
Assuming, classB is assignable to classA.
Does this mean that xyz is an instance of classB or classA? And which constructor will be call?

The object will be an instance of class B and the referenced type
is of type class A
The class B constructors will be called as the object belongs to B.
Hope this helps
