Getting HTTP response code in Java

I need to find the HTTP response code of URLs in java. I know this can be done using URL & HTTPURLConnection API and have gone through previous questions like this and this.

I need to do this on around 2000 links so speed is the most required attribute and among those I already have crawled 150-250 pages using crawler4j and don't know a way to get code from this library (due to which I will have to make connection on those links again with another library to find the response code).

In Crawler4J, the class WebCrawler has a method handlePageStatusCode, which is exactly what you are looking for and what you would also have found if you had looked for it. Override it and be happy.

The answer behind your first link contains everything you need: How to get HTTP response code for a URL in Java?

    URL url = new URL("http://google.com");
    HttpURLConnection connection = (HttpURLConnection)url.openConnection();
    connection.setRequestMethod("GET");
    connection.connect();

    int code = connection.getResponseCode();

The response code is the HTTP code returned by the server.
