overriding a method code example

Example 1: 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

Example 2: what's method overriding

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

Example 3: method overloading

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.

Example 4: method override

using method-override in your index.js
1. npm install method-override --save
2. var methodOverride = require("method-override");
3. app.use(methodOverride("_method"));
//'_method' is what methodOverride will look for
method override in your UPDATE route:

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

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
