java實現根據域名獲得ip地址代碼

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

public class GetIPAddressFromHostname {

public static void main(String[] args) {

    try {

        InetAddress inetAddr = InetAddress.getByName("open-open.com");

        byte[] addr = inetAddr.getAddress();

        // Convert to dot representation
        String ipAddr = "";
        for (int i = 0; i < addr.length; i++) {
            if (i > 0) {
                ipAddr += ".";
            }
            ipAddr += addr[i] & 0xFF;
        }

        System.out.println("IP Address: " + ipAddr);

    }
    catch (UnknownHostException e) {
        System.out.println("Host not found: " + e.getMessage());
    }

}
