Why getWindowHandles() method returns set?

[Mayur Shah]

In Selenium getWindowHandles() method returns Set, what is the reason? Why can't it return List?

[⇜Krishnan Mahadevan⇝]

List can have duplicates but Set cannot have duplicates. 

On a similar note, window handles are expected to be unique in nature (else your switch to window logic goes for a toss) and Set guarantees uniqueness.
