Close a Scanner linked to System.in

Question

I have a Scanner linked to System.in. Now, after using the Scanner, I should close it, as it is bad coding practice to leave it open.

Answer 1

Instead of adding shield classes and stuff like that, just put a nice comment and a

        @SuppressWarnings("resource")

That's good enough. And I don't seem to see a lot of drawbacks to this approach. Don't forget the comment.
