Should I close a StringReader?

Question

I use a StringReader to turn a string into something I can upload to an SFTP server (it takes a stream). Is there any point in closing that StringReader

Answer 1

If you close the stream and release any system resources associated with it. Once the stream has been closed, further read(), ready(), mark(), or reset() invocations will throw an IOException. Closing a previously closed stream has no effect. Specified by: close in interface Closeable Specified by: close in class Reader
