Closing inputstreams in Java

Question

I have the following piece of code in a try/catch block

 InputStream inputstream = conn.getInputStream();
 InputStreamReader inputstreamreader = new  InputSt         


        

Answer 1

By convention, wrapper streams (which wrap existing streams) close the underlying stream when they are closed, so only have to close bufferedreader in your example. Also, it is usually harmless to close an already closed stream, so closing all 3 streams won't hurt.
