From the JavaDoc of getResponseCode:

It will return 200 and 401 respectively. Returns -1 if no code can be discerned from the response (i.e., the response is not valid HTTP).

-1 is not a error it returns if no code can be discerned from the response, see here

URL url = new URL("any url");
HttpURLConnection conn=(HttpURLConnection) url.openConnection();
InputStream in = conn.getInputStream();
int responseCode = conn.getResponseCode();

if(responseCode == -1) {
    // no code can be discerned
}
