看InetAddress的成员方法:
public static InetAddress getByName(String host):根据主机名或者IP地址的字符串表示得到IP地址对象
举例:
public class InetAddressDemo {
public static void main(String[] args) throws UnknownHostException {
// public static InetAddress getByName(String host)
// InetAddress address = InetAddress.getByName("qinwendou");
InetAddress address = InetAddress.getByName("192.168.1.105");
// 获取两个东西:主机名,IP地址
// public String getHostName()
String name = address.getHostName();
// public String getHostAddress()
String ip = address.getHostAddress();
System.out.println(name + "---" + ip);
}
}
