Do I need to close InputStream after I close the Reader

Question

I was wondering, whether is there any need for me to close the InputStream, after I close the reader?

    try {
        inputStream = new java.io.FileInputSt         


        

Answer 1

Acordding to source sniffing the reader closes its underlying inputstream. According to javadoc it seams that InputStreamReader "closes the stream" when reader.close() is invoked.

I'm not sure if ANY Reader must close its sources when you do reader.close(). I think that this is important so your code can use a reader no matter what concrete type it is.

Anyway it makes sense that it's enforced.
