java - 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. But, if I close the Scanner, I will also be closing System.in! Can anyone tell me how I can close the Scanner without closing System.in (if there is any way).

Answer 1

One option is to wrap your System.in stream in a CloseShieldInputStream that prevents it from being closed. Your reader would then use the CloseShieldInputStream rather than the raw System.in stream.

Here is the API for the class: http://commons.apache.org/io/apidocs/org/apache/commons/io/input/CloseShieldInputStream.html
