What Happens If function have same name but different return type and different arguments.Is it overload or not.

Question

Hi Sololearn
First, thanks all of you for clearing my every doubts.

My question is that what happens if we write function have same name but different return type and different arguments.Is it overload & override or no?

Ex. Case 1:
void fun(int x, int y) // Assume in parent class
int fun( int x, int y) // Assume in child class

Case 2:
void fun ( int x, int y) // parent class
void fun (int x, float y) // child class

I think in case 1 overloading is not possible because of last Statment will changes ( return z will added in child class function). But what about overriding. Hmm I'm confused here

And for case 2: I don't have any idea.

Please answer.....

Answer 1

Neither is overriden

Override only happens when the methods are exactly same, including return type, method name, data type of arguments, etc.

Overload is a bit different. Case 2 is overload-able in both Java and C++. The difference is in C++ you need to introduce the parent method to the child in the child class, while you don't need to in Java. Case 1 is not overload-able in both langauges.

Answer 2

Please provide the language for the question.
