(JAVA)What happens with variables of the superclass when we use pholymorphism?

Question

If I have a class and, then, I created another
class like this: class [new class_name] extends [old class_name] {...etc..}. How I can use the variables of the superclass in the subclass? What are the limitations of pholymorphism? Does anyone have material about pholymorphism?

Answer 1

1. You can access super attributes by super.variableName if the access modifier of the variable is public or protected.
2. [Edit] Private variables of the super class are not inherited.
