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

The simplest thing is to not close Scanner if you don't want to close the underlying stream.

Ideally you should create just one Scanner which you use for the life of the program. In any case, it appears you don't have a good reason to close it.
