RESTful call in Java

To make a RESTful call in Java, you can use the HttpURLConnection class.

Here is an example of how to do this:

URL url = new URL("http://www.example.com/api/endpoint");
HttpURLConnection conn = (HttpURLConnection) url.openConnection();
conn.setRequestMethod("GET");

// Add request headers, if necessary
conn.setRequestProperty("Content-Type", "application/json");
conn.setRequestProperty("Authorization", "Bearer YOUR_API_KEY");

// Send the request and read the response
int responseCode = conn.getResponseCode();
if (responseCode == 200) {
   // Successful response
   InputStream inputStream = conn.getInputStream();
   // Read the response here
} else {
   // Error response
   InputStream errorStream = conn.getErrorStream();
   // Read the error response here
}

This example makes a GET request to the specified URL and reads the response. You can use other request methods, such as POST, PUT, or DELETE, by setting the setRequestMethod method to the appropriate value.

You can also send data in the request body and read data from the response body by writing to and reading from the OutputStream and InputStream of the connection, respectively.

I hope this helps! Let me know if you have any questions.
