6) Why windowHandles method return type is set?

Question

Accepted Answer

The windowHandles method returns a set of window handles as a set of strings.

The windowHandles method is used to retrieve all the window handles of the current session.
The return type is set because it ensures that each window handle is unique and there are no duplicates.
The set data structure allows for efficient retrieval and manipulation of window handles.
Example: Set handles = driver.getWindowHandles();

Accepted Answer

The windowHandles() method in Selenium returns a Set of String values representing the handles of all the windows currently open in the WebDriver instance.

The reason that the return type is a Set is because it ensures that the returned values are unique and there are no duplicates. This is important because it's possible for a single window to have multiple handles, such as when there are multiple frames within a window, or when a window is opened and closed multiple times during the test.

Using a Set also allows you to easily iterate through all the open windows and switch to a specific window by its handle, without having to worry about duplicate values or keeping track of the order of the handles.
