Hi all:

I want to open a file on the web site, copy the file to my pc, and then, read it again to do something else. Now my question is: is there anyway I can re-open the web file to read it again without having to re-declare all those streams, readers, etc.? My code is like the following:

URL u = new URL(webFilePath + fileName);
InputStream in = u.openStream();            
in = new BufferedInputStream(in);
Reader isr = new InputStreamReader(in);
BufferedReader br = new BufferedReader(isr);

//copy the file
....
br.close();

//read the file again, this time parse the line read and do something
??

Is there any way I can avoid re-declaring everything? It's no big deal to do that, but if there're smarter way to do things, I want to know.

Thanks.
