Is it necessary to close Scanner when there is no stream underlying?

Question

Directly from this Scanner API:

String input = "1 fish 2 fish red fish blue fish";
     Scanner s = new Scanner(input).useDelimiter("\\s*fish\\s*");
     System.out.println(s.nextInt());
     System.out.println(s.nextInt());
     System.out.println(s.next());
     System.out.println(s.next());
     s.close(); 

Answer 1

First we make our habits; then our habits make us.

I'd say close the stream, because ingraining a habit like closing resources in finally blocks make sense.

Answer 2

I don't think so, but it's best to close it anyway in case you change your code to use a stream. It's also a good habit, one that you really want to get into.
