Shadowing is either through scope or through inheritance. Shadowing through inheritance is hiding a METHOD of a base class and PROVIDING a new IMPLEMENTATION for the same. This is the default when a derived class writes an implementation of a method of base class which is not declared as overridden in the base class. This also serves the PURPOSE of protecting an implementation of a new method against subsequent addition of a method with the same name in the base class.’shadows’ keyword is RECOMMENDED although not necessary since it is the default.
