Why do we need to typecast the WebDriver Instance to use TakeScreenshot or JavascriptExecutor?

In this video, I have explained about "Why do we need to typecast the WebDriver instance to use TakeScreenshot or JavascriptExecutor Interface methods".

WebDriver is an interface with a set of unimplemented methods.

WebDriver drives a browser natively, as a user would, either locally or on a remote machine using the Selenium server, marks a leap forward in terms of browser automation.

Selenium WebDriver refers to both the language bindings and the implementations of the individual browser controlling code. This is commonly referred to as just WebDriver.

Selenium WebDriver is a W3C Recommendation

- WebDriver is designed as a simple and more concise programming interface.

- WebDriver is a compact object-oriented API.

- It drives the browser effectively.

When working with selenium, we typecast the webdriver instance in order to use the methods from TakeScreenshot or JavascriptExecutor interfaces.

So basically java doesn't allow us to create the interface objects, so that is the reason we always typecast the webdriver instance.

But do you know what exactly what happens when you typecast it and why we need to typecast it?

Great explanation of all important topics related to instantiation of WebDriver and typecasting I could find in one video, thank you!

Very good explanation and after watching full video came to know the main reason for typecasting. Please make more videos like this. 👍

[swayamkarnjkar]

One of the very best explanation, I have ever came across you are awesome. you should make more videos on interview questions

[AnkitSingh-bewi]

Nice explaination using interface and inheritance all together 👍
Watched twice to recollect everything together..

Superb explaination. I was wondering why we are typecasting and what is it.

Thanks, now clear.

Neat explanation 👌👏..thank you subscribed 👍

[zeeshanahmed]

Very good explanation...you are awesome...:)

[parvinkouliev]

Excellent explanation. Can you also explain why don't we just use RemoteWebDriver class to create driver instance in this case which would not need typecasting since RemoteWebDriver inherits all methods of all 3 interfaces.

[chinnikrishnad]

Wonderful HYR garu.
Then, can we directly do as following?
RemoteWebDriver driver=new RemoteWebDriver();

and use it?
Kindly reply. And, as always, Thanks for your great teaching.

Looks like there are more selenium tutorials in english playlist than the selenium telugu playlist. If there are any missed topics in telugu playlist can you do them in telugu too. Its just easy to process in telugu. and i feel because our mother tongue is telugu explanation and understanding is easier and faster in telugu.

Please consider my request.

[RAHULKUMAR-rbpl]

Sir whenever we said typecasting for javascriptExecutor in that situation to be more precise we can say it is also upcasting or not
