Converting IP Numbers to Strings

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);

}

byte[] b = local.getAddress();

String strAddress=“”;

for (int i = 0; i < b.length; i++)

strAddress += ((int)255 & b[i]) + “.”;

System.out.println (“Local = “ + strAddress);

}

}

This does things

the hard way!

Just call

getHostAddress()

instead!

Lesson: Java’s

net package has most

every method you

will need!
