I am a newbie in java and wanted to use curl in java. What is my question is curl built-in in java or I have to install it from any 3rd party source to use with Java. If so, how to install curl in java. I have been googling for a long time but didnt find any help. Hope anyone can help me out there.
Thanks in advance.

We can execute curl commands from Java by using the ProcessBuilder — a helper class for building instances of the Process class.
cURL, which stands for client URL, is a command line tool that developers use to transfer data to and from a server. At the most fundamental, cURL lets you talk to a server by specifying the location (in the form of a URL) and the data you want to send.
With ReqBin Online Curl Client, you can run Curl commands directly from your browser. No desktop apps or browser plugins required. Just enter the Curl command and click on Run. Built-in Curl command syntax Highlighter will highlight Curl command syntax while you type Curl command.
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.".
