java根据主机名获取ip

import java.net.InetAddress;
import java.net.UnknownHostException;

/*
 *  表示互联网中的IP地址
 *    java.net.InetAddress
 *  静态方法
 *    static InetAddress  getLocalHost()   LocalHost本地主机
 *    返回本地主机,返回值InetAddress对象
 *    
 *    static InetAddress getByName(String hostName)传递主机名,获取IP地址对象
 *    
 *  非静态方法
 *     String getHoustAddress()获取主机IP地址
 *     String getHoustName()获取主机名
 *
