Answers for "polymorphism in oop"

polymorphism in oop

here's a more formally written answer.

Polymorphism is the method in an object-oriented programming language
that performs different things as per the object's class, which calls it.

With Polymorphism, a message is sent to multiple class objects, and every
object responds appropriately according to the properties of the class.

what is polymorphism

The word polymorphism means having many forms. In simple words, we can define polymorphism as the ability of a message to be displayed in more than one form. Real life example of polymorphism: A person at the same time can have different characteristic. Like a man at the same time is a father, a husband, an employee.

what is polymorphism

POLYMORPHISM: It is an ability of object to behave in multiple
form. The most common use of polymorphism is Java, when a
parent class reference type of variable is used to refer to a child
class object.
In my framework
  E.g.: WebDriver driver = new ChromeDriver();
We use method overloading and overriding to achieve
Polymorphism.

There are two types of achieving Polymorphism
Upcasting & Downcasting
Upcasting is casting a subtype to a supertype, 
going up in the inheritance tree.
It is done implicitly
 in order to use method available on any
 interface/class, the object should be of
 same class or of class implementing the interface.  
   WebDriver driver = new ChromeDriver();
or
	TakeScreenShot ts = new ChromeDriver();
    
    Downcasting is casting to a subtype, 
going down in the inheritance tree.
It is done to access sub class features.
It has to be done manually

ChromeDriver driver = (ChromeDriver)Webdriver;
