Does polymorphism work when calling methods inside a superclass?

Question

Java

The question is something like this, is there a superclass

public class SuperClass {
//...
public void method0(){ /*Назовем этот блок кода А*/}
public void method1(){ this.method0() };
//...
}

And the class inherited from it

public class SubClass extends SuperClass {
//...
@Override
public void method0(){ /*А этот Б*/}
//...
}

What code will be executed as a result of the following call:

SuperClass ob = new SubClass();
ob.method1();

Answer 1

It would be faster to test it yourself by putting the output to the console in the method0 () method in the superclass and in the subclass.
Must call block B because it is a virtual method and the code version is determined by the real class of the object. Unless java has a special syntax with the this keyword.
Check it out for yourself, it will take a couple of minutes.
