class A {
  // Identical to "private" alone:
  private final void f() {
    System.out.println("WithFinals.f()");
  }

  // Also automatically "final":
  private void g() {
    System.out.println("WithFinals.g()");
  }
}

class B extends A {
  private final void f() {
    System.out.println("OverridingPrivate.f()");
  }

  private void g() {
    System.out.println("OverridingPrivate.g()");
  }
}

class C extends B {
  public final void f() {
    System.out.println("OverridingPrivate2.f()");
  }

  public void g() {
    System.out.println("OverridingPrivate2.g()");
  }
}

public class MainClass {
  public static void main(String[] args) {
    C op2 = new C();
    op2.f();
    op2.g();

    B op = op2;
    // op.f();
    // op.g();

    A wf = op2;
    // wf.f();
    // wf.g();
  }
}
