How does instance variable invocation work when you do A thing = new B(); where B is a subclass of A?

Question

This is probably answered somewhere, but I have no idea what to search for. Imagine you have the following...

The superclass, Animal.java

public class An         


        

Answer 1

This is because Java talks only about method overriding. Member variables can only be shadowed in child class. So when you say c.noise it actually refers to the string variable in parent class as the c if reference type Animal.
