What is example of method overriding in selenium webdriver? - selenium-webdriver

Question

As I went through tutorial, all written about get() method is example of method overriding.
But as per method overriding method which is present in parent class is having different implementation in child class.
And get() method is declared webdriver interface and implemented in RemoteWebDriver interface.
Then how overriding is achieved here?
Could you please help with query.
Any other example with method overriding in selenium webdriver please share?

Answer 1

If you are asking specifically for the get() function, here is the implementation tree:
public class ChromeDriver extends RemoteWebDriver
implements LocationContext, WebStorage, HasTouchScreen, NetworkConnection {...}
Here chromeDriver is an example class can be any other. It extends the RemoteDriver and implements a bunch of other interfaces. And the RemoteDriver Class extends and implements some more as below
public class RemoteWebDriver implements WebDriver, JavascriptExecutor,
FindsById, FindsByClassName, FindsByLinkText, FindsByName,
FindsByCssSelector, FindsByTagName, FindsByXPath,
HasInputDevices, HasCapabilities, Interactive, TakesScreenshot {
...
public void get(String url) {
execute(DriverCommand.GET, ImmutableMap.of("url", url));
...
}
As you can see the RemoteDriver is overrridng the get() method it gets from the WebDriver interface
public interface WebDriver extends SearchContext {
....
void get(String url);
....
}

This is a simple overriding example of the "findElement" method.
public static WebElement findElement(By Locator){
WebElement anElement = fluentWait.until(new Function<WebDriver, WebElement>() {
#Override
public WebElement apply(WebDriver webDriver) {
webDriver=sampleDriver;
return sampleDriver.findElement(Locator);
}
});
return anElement;
}

Overriding something we give different implementation in child class . And override method which was in parent.
