Polymorphism Assignment Help

Poly means many and morphism means forms therefore polymorphism means many forms. It is the skill of an entity to be in many forms.

Polymorphism in object-oriented programming follows a rule where a parent class can access an object of a child class. An entity that have more than one method is considered a polymorphic object.

Polymorphism works through a reference variable in order to achieve an objects you can communicate the methods through reference variables which is only in one type and cannot be changeable. It is also be assigned as a class or as an interface.

Types of Polymorphism:

There are several types of polymorphism which are given as following:

  1. Method overloading.
  2. Constructor overloading.
  3. Method overriding.

Method overloading:

It is a concept of object oriented programming where it is allowed in one class that contains many methods having same name but different parameters.

Parameters are also known as arguments. An example of method overloading is shown as Cat (int a, string b), Cat (int a, int b, string c) same methods name having different arguments.

Constructor Overloading:

It is a built-in method of a class to instantiate a class object and it can be many but different parameters is called constructor overloading.

You can initialize constructorwith a same name of a class otherwise your constructor will not be created properly. Public Animal (), Public Animal (int a) is the example of constructor overloading.
