java怎么获取当前ip

import java.net.*; public class Test6 { public static void main(String[] args) { // TODO Auto-generated method stub InetAddress ia=null; try { ia=ia.getLocalHost(); String localname=ia.getHostName(); String localip=ia.getHostAddress(); System.out.println("本机名称是："+ localname); System.out.println("本机的ip是 ："+localip); } catch (Exception e) { // TODO Auto-generated catch block e.printStackTrace(); } } }

java.net.InetAddress.getLocalHost().getHostAddress()
