1Interfaces specify what a class must do. 
2It is the blueprint of the class.
3It is used to achieve total abstraction. 
4We are using implements keyword for interface.

6Basic statement we all know in Selenium is
7WebDriver driver = new FirefoxDriver();
8WebDriver itself is an Interface.
9So we are initializing Firefox browser
10using Selenium WebDriver.
11It means we are creating a reference variable
12of the interface and creating an Object.
13So WebDriver is an Interface and
14FirefoxDriver is a class.
