Java 实例 – 获取指定主机的IP地址
Java 实例
以下实例演示了如何使用 InetAddress 类的 InetAddress.getByName() 方法来获取指定主机(网址)的IP地址:
/* author by w3cschool.cn GetIP.java */ import java.net.InetAddress; import java.net.UnknownHostException; public class GetIP { public static void main(String[] args) { InetAddress address = null; try { address = InetAddress.getByName ("www.w3cschool.cn"); } catch (UnknownHostException e) { System.exit(2); } System.out.println(address.getHostName() + "=" + address.getHostAddress()); System.exit(0); } }
以上代码运行输出结果为:
www.w3cschool.cn=222.73.134.120
