What is the real significance(use) of polymorphism

Question

I am new to OOP. Though I understand what polymorphism is, but I can\'t get the real use of it. I can have functions with different name. Why should I try to implement polym

Answer 1

Have you ever added two integers with +, and then later added an integer to a floating-point number with +?

Have you ever logged x.toString() to help you debug something?

I think you probably already appreciate polymorphism, just without knowing the name.
