Java 获取本机IP

import java.io.*;

import java.util.*;

import java.net.*;



public class GetIP {

    public static void main (String[] args) throws Exception {

        /*

        String s = InetAddress.getLocalHost().toString();

        System.out.println(s);

        

        String[] arr = s.split("/");

        System.out.println("host name:\n" + arr[0]);

        System.out.println("localhost IP:\n" + arr[1]);

        

        */

        Enumeration e = NetworkInterface.getNetworkInterfaces();

        while(e.hasMoreElements()) {

            NetworkInterface n = (NetworkInterface) e.nextElement();

            Enumeration ee = n.getInetAddresses();

            while (ee.hasMoreElements()) {

                InetAddress i = (InetAddress) ee.nextElement();

                System.out.println(i.getHostAddress());

            }

        }



    }

    

    

}

Linux上也适用。
