It'd be easier for people to help you if your attempt was linked via a code-playground URL.

I don't really know a lot of Java. I'm sure someone will get around to look at it.

Hello Pratik Shinde Your method is in same class like main method and it is static. So you don't need an instance of Joker. And the method returns a String: String link = extractYTId(scan); Now you can print this String to see if it works.
