This is a frequent interview question asked to all levels of experience in Selenium WebDriver. If you face this question as a beginner then the interviewer wants to check your knowledge of handling multiple windows, switching to windows, and getting the title of a window. But if you face this question as an experienced Selenium professional then you also need to exhibit your knowledge of Stream APIs of Java.
We will see sample code with and without stream usage.
