method overriding java

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

what is method overloading and method overriding in 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
