Declaring a method in sub class which is already present in parent class is known as method overriding. Overriding is done so that a child class can give its own implementation to a method which is already provided by the parent class. In this case the m
These return types are called covariant return types, and they differ in that the return type of the overriding method can be a subclass of the return type of its superclass method. We explain this with an example. Consider four classes Animal, Goat, Zoo, and PettingZoo, where Goat derived...
