Example 1: 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.
Example 2: 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
In my framework
E.g.: WebDriver driver = new ChromeDriver();
We use method overloading and overriding to achieve
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();
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;
