Here is an example code. Just handle exceptions and tweak for yourself

public class Main {


  public static void main(String[] args) {
    final String urlAdress = "http://example.com"; // url куда нужно совершить запрос
    URL url = new URL(urlAdress);
    HttpURLConnection con = (HttpURLConnection) url.openConnection();
    con.setRequestMethod("GET");
    int status = con.getResponseCode(); // совершаем запрос
    BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream())); // читаем ответ
    String inputLine;
    StringBuffer content = new StringBuffer();
    while ((inputLine = in.readLine()) != null) {
        content.append(inputLine);
    }
    in.close();
    con.disconnect();
  }

}
