how can I know the IP of the local computer, using java InetAddress
maybe or another object.
Simple:
import java.net.*;
public class Localhost {
public static void main(String[] args) throws Exception {
System.out.println(InetAddress.getLocalHost().getHostAddress());
}
}
more advanced:
import java.net.NetworkInterface;
import java.net.InetAddress;
import java.util.Enumeration;
public class NI15 {
public static void main(String[] args) throws Exception {
Enumeration e = NetworkInterface.getNetworkInterfaces();
while(e.hasMoreElements()) {
NetworkInterface ni = (NetworkInterface)e.nextElement();
System.out.println("Net interface: " + ni.getName());
Enumeration e2 = ni.getInetAddresses();
while (e2.hasMoreElements()){
InetAddress ip = (InetAddress)e2.nextElement();
System.out.println("IP address: " + ip.getHostAddress());
}
}
}
}
