Program:

            /* ............... START ............... */
                
import java.io.IOException;
import java.net.SocketException;
import org.apache.commons.net.whois.WhoisClient;

public class JavaWhoIs {
	public static void main(String[] args) {
		 
	      String domain = "example.com";
	      StringBuilder sb = new StringBuilder("");
	      WhoisClient wic = new WhoisClient();
	      try {
	         wic.connect(WhoisClient.DEFAULT_HOST);
	         String whoisData1 = wic.query("=" + domain);
	         sb.append(whoisData1);
	         wic.disconnect();
	      } catch (Exception e) {
	         e.printStackTrace();
	      }
	      System.out.println(sb.toString());
	   }
}

                /* ............... END ............... */
        

Notes:

  • WHOIS is a query and response protocol that is widely used for querying databases that store the registered users or assignees of an Internet resource, such as a domain name, an IP address block, or an autonomous system, but is also used for a wider range of other information.
