Study Notes
Polymorphism in Java
- Polymorphism allows a single action to be implemented in various ways.
- Originates from Greek words "poly" (many) and "morphs" (forms), indicating multiple forms of a concept.
Types of Polymorphism
- Compile-time Polymorphism: Achieved through method overloading. Occurs when multiple methods have the same name but different parameters within a class.
- Runtime Polymorphism: Known as Dynamic Method Dispatch, where method calls to overridden methods are resolved during runtime, rather than compile time.
Method Overloading vs. Method Overriding
- Method Overloading: Demonstrates compile-time polymorphism, allowing methods with the same name but different signatures within the same class.
- Method Overriding: Involves redefining a method from a superclass in its subclass, key to achieving runtime polymorphism.
