Extreme Java When vanilla Java is not enough

URL url = new URL(FORM_URL);
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
 
OutputStreamWriter out = new OutputStreamWriter(conn.getOutputStream());
out.write("field=value&field=value&...");
out.flush();
 
InputStreamReader isr = new InputStreamReader(conn.getInputStream());
BufferedReader in = new BufferedReader(isr);
String line;
 
while ((line = in.readLine()) != null) {
    // do something
}
 
out.close();
in.close();
