method overriding java
Method overloading is providing two separate methods in a class with the same name but different arguments, while the method return type may or may not be different, which allows us to reuse the same method name.
Method overriding means defining a method in a child class that is already defined in the parent class with the same method signature, same name, arguments, and return type

In my framework==
I use implicit wait in Selenium. Implicit wait
is an example of overloading. In Implicit wait
we use different time stamps such as SECONDS, MINUTES, HOURS etc.,
A class having multiple methods with
same name but different parameters
is called Method Overloading
Thank you!

Method Overloading:
Access modifier can be same or different,
Return-Type can be same or different,
Parameters MUST be different, Method name MUST be same,
any method can be overloaded
Method Overriding:
After a method is inherited it is possible to change
the implantation of the method in the child class.
This concept is called overriding.
Method name, Parameter, and Return-Type MUST be same
access modifier MUST be same or more visible,
MUST happen in the sub class,
ONLY the instance methods can be overridden
@Override annotation MUST be applicable.
Static and Constructor cannot be override.
We can use the @Override annotation before the method
to declare the overriding.
EXAMPLE: get method WebDriver driver = new ChromeDriver();
driver.get("URL") ==> opens the url from chrome

Overriding means same method name and same parameter,
occur in different class that has inheritance relationship.
we use method overriding to implement specific functionality to the method.
Example: get method
WebDriver driver = new ChromeDriver();
driver.get("URL") ==> opens the url from chrome
WebDriver driver = new FireFoxDriver();
driver.get("URL") ==> opens the url from Firefox
we can only override instance methods and method override
takes place in sub class.
instance method that we are going to override cannot be private and final
Thank you!

occur in different class that has
inheritance relationship.
we use method overriding to implement
specific functionality to the method.
Examples are get and navigate methods
of different drivers in Selenium .
Example: get method
WebDriver driver = new ChromeDriver();
driver.get("URL") ==> opens the url from chrome
WebDriver driver = new FireFoxDriver();
driver.get("URL") ==> opens the url from Firefox
we can only override instance methods and method override
takes place in sub class.
instance method that we are going to override cannot be private and final
Example: get method
WebDriver driver = new ChromeDriver();
driver.get("URL") ==> opens the url from chrome
