What is Function overriding and Overloading?

Question

Accepted Answer

Function overriding is when a subclass provides a different implementation of a method already defined in its superclass. Function overloading is when multiple methods with the same name but different parameters are defined in a class.

Function overriding is used to achieve runtime polymorphism.
In function overriding, the method signature remains the same but the implementation is different in the subclass.
Function overloading is used to achieve compile-time polymorphism.
In function overloading, methods with the same name but different parameters are defined in the same class.
Function overloading allows a method to perform different tasks based on the number and type of parameters passed.
Example of function overriding: class Animal { void sound() { System.out.println('Animal makes sound'); } } class Dog extends Animal { void sound() { System.out.println('Dog barks'); } }
Example of function overloading: class Calculator { int add(int a, int b) { return a + b; } double add(double a, double b) { return a + b; } }
