Overriding is a feature that is available while using Inheritance. It is used when a class that extends from another class wants to use most of the feature of the parent class and wants to implement specific functionality in certain cases. In such cases we can create methods with the same name and signature as in the parent class.
Dec 26, 2013 · 8. Static Polymorphism: is where the decision to resolve which method to accomplish, is determined during the compile time. Method Overloading could be an example of this. Dynamic Polymorphism: is where the decision to choose which method to execute, is set during the run-time.
Oct 1, 2008 · Method overloading. Method overloading means writing two or more methods in the same class by using same method name, but the passing parameters is different. Method overriding means we use the method names in the different classes,that means parent class method is used in the child class. In Java to achieve polymorphism a super class reference ...
Oct 9, 2009 · 1. Method overriding in Java is a concept based on polymorphism OOPS concept which allows programmer to create two methods with same name and method signature on interface and its various implementation and actual method is called at runtime depending upon type of object at runtime.

In this case, you're not overriding the parent method, but hiding it. Example from OCP Java 7 book, page 70-71:
Sep 20, 2011 · Polymorphism is a concept of object oriented programming that allows a field, in this case, an object, to be changed from one form to another. Poly = multiple, morph = change.
