Runtime Polymorphism

Method Overloading vs Overriding

Method overloading is defining multiple methods with the same name but different parameter lists within a class, resolved at compile time, while method overrid…

What is Method Overriding in OOP?

Method overriding is when a subclass provides its own implementation of a method already defined in its superclass, using the same name and signature.

What is Polymorphic Dispatch?

Polymorphic dispatch is the runtime mechanism by which a call to a method through a base-type reference or interface is routed to the specific implementation d…

Static Binding vs Dynamic Binding

Static binding resolves which method or variable a call refers to at compile time based on the declared type, while dynamic binding defers that resolution unti…

Early Binding vs Late Binding

Early binding (also called static binding) connects a method call to its implementation at compile time, while late binding (also called dynamic binding) conne…

What is a Vtable (Virtual Method Table)?

A vtable (virtual method table) is a per-class array of function pointers that maps each virtual method to its actual implementation, used by the runtime to pe…

How Do Virtual Method Tables (vtables) Work?

A virtual method table (vtable) is a per-class array of function pointers that the runtime consults through a hidden pointer stored in each object, allowing a…

What is Function Overriding vs Shadowing?

Overriding replaces a parent’s virtual method implementation such that the subclass version runs even when called through a base-type reference, while shadowin…

What is Double Dispatch in OOP?

Double dispatch is a technique where the method that executes is selected based on the runtime types of TWO objects involved in a call, not just one, achieved…
