Is it something like this kindly help

Question

A object = new B(); // reference of class A but calling B class constructor so creating object of Class B using reference of class A.

B b = (B) object; // so if we create totally b class object then we will create like B b = new B();
As we can see new B(); is already initialized in object.

Answer 1

If B is a subclass of A, then your code is fine. The comments are accurate for that code.

Answer 2

Yes, it is.
Thanks
