Polymorphism in object-oriented programming allows uniform handling of diverse object types through shared interfaces or base classes, enabling interchangeable components. Use it to design flexible, extensible systems where new types can be added without modifying core processing logic.

You can implement polymorphism using interfaces in Java and protocols or abstract base classes in Python. These define common contracts and enforce structural consistency across derived classes, allowing different implementations to be processed uniformly through a shared type.

Method overloading defines multiple methods with the same name but different parameters, common in Java and C#. Operator overloading assigns custom behavior to operators like addition, supported in C# and Python, allowing objects to interact with standard operators naturally.

Yes, you can build a payment processing system using interface-based polymorphism across Java, Python, TypeScript, and C#. By defining a common PaymentMethod interface, different payment types like credit cards or PayPal can be handled uniformly and extended easily.

Yes, this Skill demonstrates polymorphism concepts across multiple languages including TypeScript and C#. It covers interface-based polymorphism in TypeScript and both method and operator overloading techniques in C#.

You should avoid abstract base classes when a lightweight protocol or interface is sufficient, or when your language supports duck typing like Python. Abstract classes enforce strict inheritance hierarchies, which can reduce flexibility compared to standalone interfaces.
