Polymorphism Part 1: Method Overloading in C# Method Overriding means having multiple methods with the same signature, one method to be present in base class and the other in derived class. This can be achieved by using Virtual and Override keywords. Here, the same signature applies to:...
Let's assume the following simple class hierarchy with classesA,BandCfor the discussions in this text.Ais the super- or base class,Bis derived fromAandCis derived from classB. In some of the easier examples, we will only refer to a part of this class hierarchy. Inherited Methods A metho...

Overriding Abstract Methods In Java, abstract classes are created to be the superclass of other classes. And, if a class contains an abstract method, it is mandatory to override it. We will learn more about abstract classes and overriding of abstract methods in later tutorials. ...

4. Design Patterns Overriding plays a key role in the Template Method pattern by defining the overall structure of an algorithm in a base class, while permitting subclasses to override specific steps. The Strategy pattern leverages overriding to encapsulate various algorithms and enable their interchang...
When overriding methods in Java, the access level can’t be more restrictive in the subclass. For example, if the method in the parent class ispublic, the overridden method in the subclass can’t beprivateorprotected. However, it can bepublic. ...
