What's the correct way to handle abstract classes without using protected?

Question

For example:

public abstract class SomeBaseClass extends Fragment {
   protected static final String INT_TAG = "int_tag";
   protected int someInt;

   //...
}

public class ChildClass extends SomeBaseClass {
    public static ChildClass newInstance(int argInt) {
        Bundle args = new Bundle();
        bundle.putInt(INT_TAG, argInt);
        ChildClass fragment = new ChildClass();
        fragment.setArgs(args);
        return fragment;
    }

    public void onCreate() {
        someInt = getArguments().getInt(INT_TAG);
    }

    //...
}

However I've heard that it's a bad idea to use protected variables in abstract classes for some reason (I don't know why). What's the alternative?

Answer 1

It's a bad idea to access protected attributes because it breaks the encapsulation, making your strongly coupled. Still, you can access your protected fields using getters and setters.
