How to use cURL in Java?

I want to use curl in java. Is curl built-in with Java or I have to install it from any 3rd party source to use with Java? If it needs to be separately installed, how can that be done?

Solution

  • You can make use of java.net.URL and/or java.net.URLConnection.

    URL url = new URL("https://stackoverflow.com");

try (BufferedReader reader = new BufferedReader(new InputStreamReader(url.openStream(), "UTF-8"))) {
    for (String line; (line = reader.readLine()) != null;) {
        System.out.println(line);
    }
}

    Also see the Oracle's simple tutorial on the subject. It's however a bit verbose. To end up with less verbose code, you may want to consider Apache HttpClient instead.

    By the way: if your next question is "How to process HTML result?", then the answer is "Use a HTML parser. No, don't use regex for this.".
