This week's book giveaway is in the OO, Patterns, UML and Refactoring forum. We're giving away four copies of Refactoring for Software Design Smells: Managing Technical Debt and have Girish Suryanarayana, Ganesh Samarthyam & Tushar Sharma on-line! See this thread for details.
You just answered your own query, if classes are in different packages, then protected members can only be accessed by subclasses, in your example main method is in the same class(demo2) hence can access i.
That's a normal behavior. Remeber this : Subclasses outside the package CAN'T USE A SUPERCLASS REFERENCE to access a protected member (as said at page 36 of the scjp 5 book of Kathy sierra and Bert Bates).
Hope this will help
