Does a subclass of a custom fragment call the saveInstanceState method of its super class?

So I have a class that extends fragment

public class General_Fragment extends Fragment{

    int i;

    @Override
    public void onSaveInstanceState(@NonNull Bundle outState) {
        outState.putInt(INTEGER_KEY, getInt());
        super.onSaveInstanceState(outState);
    }

    public int getInt(){
        return i;
    }

    …
}

And another class that extends this first class.

public class Specific_Fragment extends General_Fragment{
    int j;

    @Override
    public int getInt(){
        return j;
    }

    …
}

When the Specific Fragment is destroyed the General_Fragments onSavedInstanceState should be called correct? Or do I need to implement something in the subclass to call the superclass method?

No you don't need to override it to be called, it's inherited from its parent class which is General_Fragment

If you do not override the onSaveInstanceState method in Specific_Fragment, the one implemented in General_Fragment will be called.

So there's no need to override it, as long as you don't need to save something else that from the most derived fragment.
