Java如何將主機名改為其特定的IP地址?

解決方法

下麵的示例演示如何net.InetAddress類的InetAddress.getByName()方法將主機名變更其特定的IP地址。

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.gitbook.net");
      }
	  catch (UnknownHostException e) {
         System.exit(2);
      }
      System.out.println(address.getHostName() + "="
      + address.getHostAddress());
      System.exit(0);
   }
}

結果

上麵的代碼示例將產生以下結果。

http://www.gitbook.net = 112.124.103.85
