Contoh pemrograman Java untuk mencari IP Address sebuah komputer jika diketahui nama komputer tersebut dengan menggunakan kelas InetAddress.
Source Code:
import java.net.*;
public class urltest2 {
public static void main (String args[]) {
URL webURL, ftpURL;
String url = "http://myname:mypass@www.example.com:81/a/bc/def/vendor.html?search=a#AKHIR";
if (args.length == 1) url = args[0];
try {
webURL = new URL(url);
System.out.println("URL = " + webURL);
String auth, file, host, path, protocol, query, ref, user;
auth = webURL.getAuthority();
System.out.println("Authority = "+ auth);
protocol = webURL.getProtocol();
System.out.println("Protocol = "+ protocol);
user = webURL.getUserInfo();
System.out.println("User Info = "+ user);
host = webURL.getHost();
System.out.println("Host = "+ host);
int port, def_port;
port = webURL.getPort();
if (port == -1) port = webURL.getDefaultPort();
System.out.println("Port = "+ port);
file = webURL.getFile();
System.out.println("File = "+ file);
path = webURL.getPath();
System.out.println("Path = "+ path);
query = webURL.getQuery();
System.out.println("Query = "+ query);
ref = webURL.getRef();
System.out.println("Ref = "+ ref);
}
catch (MalformedURLException e) {
System.err.println("URL Salah");
}
}
