What is method overriding and overloading

Question

Accepted Answer

Method overriding is when a subclass provides a specific implementation of a method that is already provided by its parent class. Method overloading is when multiple methods have the same name but different parameters.

Method overriding is used for runtime polymorphism.
Method overloading is used for compile-time polymorphism.
Example of method overriding: public class Animal { public void sound() { System.out.println("Animal makes a sound"); } } public class Dog extends Animal { public void sound() { System.out.println("Dog barks"); } }
Example of method overloading: public class Calculator { public int add(int a, int b) { return a + b; } public double add(double a, double b) { return a + b; } }
