Address representations

java.net.InetAddress:

-- A class representing an IP address

-- Performs validity checking on IP names

-- Thus, there are no public constructors!

-- Instead, just call a static class method

to obtain an InetAddress:

import java.net.*;

public class MyMachineName {

public static void main (String arg[]){

InetAddress local = null;

try {

local = InetAddress.getLocalHost();

} catch (UnknownHostException e){

System.err.println ("Identity Crisis!");

System.exit(0);

}

String strAddress = local.getHostName();

System.out.println ("Local Host = " + strAddress);

}

InetAddress

has no public

constructors

since it performs

validity checking

of all IP names
