close stream

Hi,

I have this simple case to read an output stream of an external process:

Process proc = Runtime.getRuntime().exec(parameters);

InputStream is = proc.getInputStream();

InputStreamReader isr = new InputStreamReader(is);

BufferedReader br = new BufferedReader(isr);

String line = null;

while ((line = br.readLine()) != null) {

// do something

}

br.close();

isr.close();

is.close();

is it necessary close is, isr and br? Or is it enough close br only?

Thanks,

Giulio
