Using cURL in Java: How-to and Implementation

Question:

Can cURL be integrated with Java, and if so, how can it be installed and utilized?

Answer:

While cURL is not natively built into Java, it can be easily accessed through other available libraries. One option is to utilize the java.net.URL and java.net.URLConnection classes:

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);
    }
}

Alternatively, Apache HttpClient provides a concise and effective interface for HTTP requests:

HttpClient client = HttpClientBuilder.create().build();
HttpResponse response = client.execute(new HttpGet("https://stackoverflow.com"));
