java.io.BufferedReader.readLine() consuming 99% CPU Why?

In this code i am reading a value from stream. But readline() method is taking more CPU.Can you help me why is this so and give me suggession to minimize CPU usage.

    HttpURLConnection request = (HttpURLConnection) url.openConnection();
    request.setRequestMethod("POST");
    request.setRequestProperty("Content-Length", "0");
    request.setUseCaches(false);

    InputStreamReader in = new InputStreamReader((InputStream) request.getContent());
    BufferedReader buff = new BufferedReader(in);  

    while(line = buff.readLine() != null) {
   System.out.print("hello");
    }

I'm pretty sure the print statement is the reason for the high cpu load. What happens if you remove it?

You should be attaching the BufferedReader to the input stream of the request, but I find it hard to believe the statement in your title.
