We use method overriding to implement run time polymorphism or late binding. The following code snippet shows how the Log method can be called using a reference of the base class. static void Main(string[] args) { Logger logger = new FileLogger(); logger.Log("Hello World!"); Console....

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...

Understanding of Object-Oriented Programming (OOP): In order to build for Android, one must have a thorough understanding of object-oriented programming (OOP) principles. The cornerstone for writing clear and maintainable code is OOP. Encapsulation, inheritance, and polymorphism are key ideas that mu...
But you should avoid using instanceof anyway, because there are almost always better ways to solve problems for which you think you need it (you can often use polymorphism instead). Jon Camilleri wrote:2. How is it possible to implement a generic swap algorithm, ... That example code ...
