这是我的一个网站的代码，但我需要在同一个 try and catch 中创建多个 ip

package javaapplication1;

import java.net.InetAddress;
import java.net.UnknownHostException;

public class JavaApplication1 {

    public static void main(String[] args) {
         try {
            InetAddress[] addresses = InetAddress.getAllByName("google.com");

            for (InetAddress address : addresses) {
                System.out.println(address);


            }
        } catch (UnknownHostException ex) {
            System.out.println("Could not find");
        }
    }
}

Answer 1

制作 Facebook、Google 和 yahoo 的列表

迭代列表，然后使用InetAddress.getAllByName(list.get(index))

ArrayList<String> list = new ArrayList<>();
        list.add("Facebook");// can add more urls
        for (String ip : list) {
            try {
                InetAddress[] addresses = InetAddress.getAllByName(ip);

                for (InetAddress address : addresses) {
                    System.out.println(address);

                }
            } catch (UnknownHostException ex) {
                System.out.println("Could not find");
            }
        }
