What is polymorphism? Polymorphism is a concept in object-oriented programming that allows objects of different types to be treated as objects of a common superclass. It enables code reusability and flexibility by allowing multiple classes to implement the same method in different ways. This concept...
Polymorphism in Java Classes Polymorphism in Java is a concept by which we can perform a single action in different ways. We can process objects differently based on their data type. In other words, polymorphism allows us to define one interface and have multiple implementations. ...

Abstract classes play a key role in achieving this polymorphism by defining method signatures that derived classes must implement. It facilitates generic references to abstract class types, allowing for dynamic method invocation based on the specific subclass. ...
