Java程序可以找到以下网站的IP地址:Facebook、谷歌、雅虎在相同的尝试和捕获

Question

这是我为一个网站编写的代码，但我需要在同一个尝试中制作多个ip并捕获

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

列出Facebook、谷歌和雅虎的

遍历列表，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");
            }
        }
