Polymorphism is a very important concept in programming. It refers to the use of a single type entity (method, operator or object) to represent different types in different scenarios. Let's take an example: Example 1: Polymorphism in addition operator We know that the+operator is used extensiv...

C++ programming provides a good example of polymorphism. In this language, the plus sign (+) is anoperatorand a simple named function. It can be assigned to operate on two objects, adding them together, and it also can performBooleansearching. In the latter case, the + sign can indicate ...
Polymorphism is primarily associated with OOP paradigms, but the concept can be applied to other programming paradigms too. In functional programming, for example, polymorphism can be achieved through higher-order functions or parametric polymorphism. Although the implementation may vary, the core idea ...
The "@Override" is known as annotation (introduced in JDK 1.5), which asks compiler to check whether there is such a method in the superclass to be overridden. This helps greatly if you misspell the name of the method to be overridden. For example, suppose that you wish to override met...
In practice,interfaceare used quite often butabstractis not. A lot of objects have the same interface, but only a small number of them are organized into a hierarchy. The reason to favor which one is out of the scope of this article. For those new to the OOP concept, practical experienc...
Polymorphism shouldn't be a new concept to anybody. You deal with it every day in the real world. There's more than one class of cat to skin, but you skin 'em the same way, even if the specific instance is completely new to you. Let's say for example you want to fuck a hole....
When a message can be processed in different ways is called polymorphism. Polymorphism means many forms. Polymorphism is one of the fundamental concepts of OOP. Polymorphism provides following features: It allows you to invoke methods of derived class through base class reference during runtime. ...
For example, imagine a family of abstract vehicles that includes a couple of certain types: a car and a helicopter. The command to move from point A to point B will be executed by them equally well, but the car will make its way on the ground, and the helicopter in the air. ...
