when you open a connection via URLConnection to read the content of a Webpage, 

try {
     URL url = new URL("https://stackoverflow.com/questions/46939965/does-java-urlconnection-send-metadata");
     URLConnection urlConnection = url.openConnection();
     HttpURLConnection connection;
     connection = (HttpURLConnection) urlConnection;

     BufferedReader in = new BufferedReader(
        new InputStreamReader(connection.getInputStream()));
     String current;

     while((current = in.readLine()) != null) {
        urlString += current;
     }
  }catch(IOException e) {
     e.printStackTrace();
  }

what will Java leave for Information?
Will statistical data like the Webbrowser saved? Will that be the "Java"?

Thx for help,

HTTP "metadata" is normally sent in the headers. The one that would indicate the web browser is typically called "USER_AGENT." I do not believe Java will populate these headers for you implicitly.
