RE: Virtual Function

Posted by Kishori Sharan on August 16, 2000 at 2:40 PM

In C++ virtual function has the following meaning:
"A virtual function is a member function that you expect to be redefined in derived classes. When you refer to a derived class object using a pointer or a reference to the base class, you can call a virtual function for that object and execute the derived class's version of the function."
In java, you don't need to declare a method as virtual. This is the default behaviour. If you don't want a function to be vitual you declare it as final in java. In java if you define a method in descendent with the same signature as in ancestor then it automatically overrides the ancestor method.
