Polymorphism & Dynamic Binding
Understand polymorphism: one interface, many implementations. Learn dynamic binding where the method that runs depends on the object type.
Definition
Polymorphism means one reference type can point to objects of different subclasses. When you call a method, the correct version runs based on the actual object, not the variable type.
Why useful?
This lets you write code that is flexible and reusable. For example, a List of Animal can hold Dogs and Cats, and calling speak() works correctly for each. You do not need separate code paths.
