Is it possible to hide or lower access to Inherited Methods in Java?

Question

I have a class structure where I would like some methods in a base class to be accessible from classes derived directly from the base class, but not classes derived from der

Answer 1

It is possible, but requires a bit of package manipulation and may lead to a structure that is a bit more complex than you would like to work with over the long haul.

consider the following:

---

package a;

public class Base {
    void myMethod() {
        System.out.println("a");
    }
}

---

package a;

public class DerivedOne extends Base {
    @Override
    void myMethod() {
        System.out.println("b");
    }
}

---

package b;

public class DerivedTwo extends a.DerivedOne {
    public static void main(String... args) {
        myMethod(); // this does not compile...
    }
}

I would recommend being nice to yourself, your co-workers and any other person that ends up having to maintain your code; rethink your classes and interfaces to avoid this.
