1Method 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.

3Method 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

1Method Overloading: 
2Access modifier can be same or different, 
3Return-Type can be same or different, 
4Parameters MUST be different, Method name MUST be same, 
5any method can be overloaded
6
7Method Overriding:
8After a method is inherited it is possible to change 
9the implantation of the method in the child class. 
10This concept is called overriding. 
11Method name, Parameter, and Return-Type MUST be same
12access modifier MUST be same or more visible, 
13MUST happen in the sub class, 
14ONLY the instance methods can be overridden
15@Override annotation MUST be applicable. 
16Static and Constructor cannot be override.
17We can use the @Override annotation before the method 
18to declare the overriding.
19EXAMPLE: get method WebDriver driver = new ChromeDriver(); 
20driver.get("URL") ==> opens the url from chrome

1Overriding means same method name and same parameter, 
2occur in different class that has 
3inheritance relationship. 
4we use method overriding to implement 
5specific functionality to the method. 
6
7Examples are get and navigate methods
8of different drivers in Selenium .

10Example: get method
11WebDriver driver = new ChromeDriver();
12driver.get("URL") ==> opens the url from chrome
13
14WebDriver driver = new FireFoxDriver();
15driver.get("URL") ==> opens the url from Firefox
16
17we can only override instance methods and method override 
18takes place in sub class.
19instance method that we are going to override cannot be private and final
20Example: get method
21WebDriver driver = new ChromeDriver();
22driver.get("URL") ==> opens the url from chrome
23
24WebDriver driver = new FireFoxDriver();
25driver.get("URL") ==> opens the url from Firefox
26
27we can only override instance methods and method override 
28takes place in sub class.
29instance method that we are going to
30override cannot be private and final
