This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
The code is giving Compiler Error because the method say() in Super is available to SubTwo & SubOne via inheritance though its access is protected. So you do not need any reference to access them, they can be access just be their name.

Let me rephrase it The line 7 and 8 gives error because you can acces a protected method only via class object (SubTwo) which has inherited it and not by directly creating a object of a class directly (Super, SubOne)in a different package.

I have slightly modified the code.
Thanks. I kind of rememeber something about accesing protected members through inheritance and not by reference... But i still can't the right statement for acessing say() in Super and SubOne class.
If i could get some help with that.... [ September 11, 2008: Message edited by: Nabila Mohammad ]

For the code you provided at the start, you can access the say() of Super by say("Java")...

Hi Paul, Thanks for the explanation. I had already gone through the website as well as the K&B.
However they have both mentioned accessing variable in the Parent class- which has not been re defined in the child class.
If i have defined a say() method in all the three classes - Super,Subone and SubTwo Or a variable s in all the three - that case how do I call the variable or method in Super or SubOne class because it will always give the value of SubTwo.I mean is it even possible!?
