一、InetAddress：互联网协议 (IP) 地址；java.net包；
二、获取对象方法：
//没有构造方法；
（1）static InetAddress getLocalHost()；获取本机IP地址；//InetAddress lh = InetAddress.getLocalHost();
（2）static InetAddress getByName(String host)；根据主机名获取IP地址；
（3）static InetAddress[] getAllByName(String host)；根据主机名获取多个IP地址；
public class Test { public static void main(String[] args) throws UnknownHostException { InetAddress localHost = InetAddress.getLocalHost(); System.out.println(localHost); InetAddress byName = InetAddress.getByName("DESKTOP"); System.out.println(byName); InetAddress[] allByName = InetAddress.getAllByName("DESKTOP"); System.out.println(Arrays.toString(allByName)); } }
三、方法：
（1）String getHostName()；获取此IP的主机名；//lh.getHostName();
（2）String getHostAddress()；获取IP的字符串类型；
public class Test { public static void main(String[] args) throws UnknownHostException { InetAddress localHost = InetAddress.getLocalHost(); System.out.println(localHost.getHostName()); //DESKTOP System.out.println(localHost.getHostAddress()); //192.168.0.0 } }
