JAVA#InetAddress类'札记

 public static void main(String[] args) throws Exception {
        InetAddress inetAddress = InetAddress.getByName("www.hupu.com");//InetAddress用来代表IP地址。一个InetAddress的对象即为一个ip地址
        System.out.println(inetAddress);
        System.out.println(inetAddress.getHostName());//获取IP地址对应的域名
        System.out.println(inetAddress.getHostAddress());//获取IP地址

        InetAddress inetLocal=InetAddress.getLocalHost();
        System.out.println(inetLocal);
        System.out.println(inetLocal.getHostName());//获取IP地址对应的域名
        System.out.println(inetLocal.getHostAddress());//获取IP地址

    }
}
