获取主机名和ip

import java.net.InetAddress; public class GetHost { /** * @param args * @throws Exception */ public static void main(String[] args) throws Exception { // TODO Auto-generated method stub //获取本地主机信息； InetAddress ii = InetAddress.getLocalHost(); //获取主机为www.baidu.com的信息； InetAddress iii = InetAddress.getByName("www.baidu.com"); //获取主机ip为127.0.0.1的信息 InetAddress i = InetAddress.getByName("127.0.0.1"); System.out.println(i.getHostAddress()); System.out.println(i.getHostName()); } }
