what is difference between overloading and overriding ?

Question

Accepted Answer

Overloading is having multiple methods with the same name but different parameters. Overriding is having a method in child class with the same name and signature as in parent class.

Overloading is compile-time polymorphism while overriding is runtime polymorphism.
Overloading is done in the same class while overriding is done in different classes.
Overloading is used to provide different implementations of the same method while overriding is used to provide a specific implementation of a method in a subclass.
Example of overloading: public void print(int num) and public void print(String str)
Example of overriding: public class Animal { public void makeSound() { System.out.println('Animal is making a sound'); } } public class Dog extends Animal { public void makeSound() { System.out.println('Dog is barking'); } }
