LISTING PROGRAM IPtoName

import java.net.*;

public class IPtoName {

public static void main(String args[]) {

if (args.length == 0) {

System.out.println("Pemakaian: java IPtoName <IP address>");

System.exit(0);

}

String host = args[0];

InetAddress address = null;

try {

address = InetAddress.getByName(host);

} catch (UnknownHostException e) {

System.out.println("invalid IP - malformed IP");

System.exit(0);

}

System.out.println(address.getHostName());

}

}

LOGIKA PROGRAM

import java.net.*;

public class IPtoName {

public static void main(String args[]) {

if (args.length == 0) {

System.out.println("Pemakaian: java IPtoName <IP address>");

System.exit(0);

}

Pada sintax diatas terdapat package .net. classnya bernama IPtoName. Lalu program akan membaca percabangan untuk args sama dengan 0, maka akan di cetak IP addressnya.

String host = args[0];

InetAddress address = null;

try {

address = InetAddress.getByName(host);

} catch (UnknownHostException e) {

System.out.println("invalid IP - malformed IP");

System.exit(0);

}

System.out.println(address.getHostName());

}

}

Pada sintax diatas terdapat string host untuk array 0 dan inetadressnya null, maka addressnya akan di ambil by name, apa bisa terjadi exception maka akan di cetak invalid IP address.
