InetAddress对象,无构造函数,有非静态方法,
通过其静态方法返回实例对象InetAddress i = InetAddress.getLocalHost();//获取本地主机信息,包含主机名和主机地址
InetAddress i = InetAddress.getByName("www.baidu.com");//也可以写IP地址
InetAddress[] i = InetAddress.getAllByName("www.baidu.com");//主机若存在多个IP的之后使用这个
i.getHostAddress(); //获取主机地址
i.getHostName(); //获取主机名,当没解析出主机名时,和主机地址一样
示例:
import java.net.InetAddress; public class InetAddressDemo { public static void main(String[] args) throws Exception { InetAddress[] i = InetAddress.getAllByName("www.baidu.com"); for(InetAddress ip : i) { System.out.println(ip.getHostAddress()); System.out.println(ip.getHostName()); } } }
