Is Selenium WebDriver an interface or a class?

1.	Is Selenium WebDriver an interface or a class?
Answer» SELENIUM WebDriver is USUALLY a SET of methods defined by an INTERFACE. The browser-specific classes, on the other hand, provide an implementation of it by extending a class. AndroidDriver, ChromeDriver, FirefoxDriver, InternetExplorerDriver, SafariDriver, and others are some of the implementation classes.
