I believe it is incorrect to imply that polymorphism is specific to classes and/or object-oriented programming, seeing how ad hoc polymorphism or parametric polymorphism do not necessarily require classes and/or objects. I think what this answer is talking about is subtyping (also known as subtype polymorphism or inclusion polymorphism).
18 The main difference is polymorphism is a specific result of inheritance. Polymorphism is where the method to be invoked is determined at runtime based on the type of the object. This is a situation that results when you have one class inheriting from another and overriding a particular method.
65 Polymorphism means more than one form, same object performing different operations according to the requirement. Polymorphism can be achieved by using two ways, those are Method overriding Method overloading Method overloading means writing two or more methods in the same class by using same method name, but the passing parameters is different.
Polymorphism is one of the tenets of Object Oriented Programming (OOP). It is the practice of designing objects to share behaviors and to be able to override shared behaviors with specific ones. Polymorphism takes advantage of inheritance in order to make this happen. In OOP everything is considered to be modeled as an object. This abstraction can be taken all the way down to nuts and bolts ...
For ad-hoc polymorphism there's also the question of whether the resolution of implementation code happens at run-time (dynamic) or compile-time (static). Method overloading is generally static, and method overriding is dynamic. This is where the terms static/compile-time polymorphism and dynamic/run-time polymorphism come from.
Can anyone please give me a real life, practical example of Polymorphism? My professor tells me the same old story I have heard always about the + operator. a+b = c and 2+2 = 4, so this is polymorp...
Polymorphism is the idea of having mutiple implementation of same abstract concept. It can be static polymorphism as in method overloading and operator overloading or it can be dynamic polymorphism as in method overriding or design pattarsn like strategy pattern.
Actually, C++ has four kinds of polymorphism: parametric (genericity via templates in C++), inclusion (subtyping via virtual methods in C++), overloading and coercion (implicit conversions). Conceptionally, there is little distinction between function overloading and operator overloading.
Polymorphism (both runtime and compile time) is necessary in Java for quite a few reasons. Method overriding is a run time polymorphism and overloading is compile time polymorphism.
