Hi Cheong, You can override a protected non-static method as long as it's not marked "final". A subclass inherits all of the public and protected members of its parent, no matter what package the subclass is in. If the subclass is in the same package as its parent, it also inherits the package-private members of the parent. You can use the inherited members as is, replace them, hide them, or supplement them with new members: [1] Farrukh References: [1] http://download.oracle.com/javase/tutorial/java/IandI/subclasses.html > > Cheers > > Cheong Hee > _______________________________________________ > Do not post admin requests to the list.
