why we need method overloading

Hi ,

Method overloading Provides You same Method with Different Signature(Signature means No Of parameter, type of parameter and order of parameter). Just Like In Your Example  

You created Add Method that is taking 2 and 3 parameter.

By taking same name  programmer should not  to worry about remembering method name.

Depend on your parameter that overloaded method will call.

Hi Vamshi,

 

Both the methods are doing same operations. rather than using different method name to perform same operation you can use the same method name and pass different number of parameters. It is the easy way of programming.  

 

For demo please see https://dotnetfiddle.net/WGYhfk 

 

Thanks,

Hi Vamsi,

 

I hope you good in OOPs, class design.  

 

Why we go for class? 

  we wanna do some task or set of tasks, but that task should be well organised. So we used lot's techniques like OOPs, SOLID, Patterns, Frameworks, etc...

 

Polymorphism is the technique we  can do different behaviour to the same interface in by using different context.

Hi,

 

 Well, one obvious advantage I can think of is that you don't have to think for a name for every method just remember one method name for exp: i have a sendmail method like this

 

public void sendmail (body, to, from)

{

}

 

public void sendmail(body,to,from,attachment)

{

}

 

public void sendmail(bod,to,from,attachment,cc)

{

 

}

 

so here is 3 method with same name you just have to pass different signs even you just hv to remember one method name but just think if i gave different name of every method from that you have to remember at least 3 method name so what is more easy 1 method name  or 3 method name.I think you get the point Basically, what it does here is improve consistency and readability. 

1)Overloading has nothing to do with OOP, ever.
2) It's good to understand that "overloading" is just a bad term, because nothing is actually "loaded"; the sensible explanation of the term is merely "having methods of different signatures using the same name".
