XML 入力 : http://maps.googleapis.com/maps/api/geocode/xml?address=Connaught+Place,+New%20+Delhi,+India&sensor=true

JAXB を使用して、この XML (上記のリンク) からデータを取得しようとしています。私の目標は、特定の住所の緯度と経度を取得することです。

これらのクラスを作成しましたが、バインディング アノテーションがありません。これを入手するのを手伝ってください、事前に感謝します

編集：コードが機能するようになったので、回答に新しいコードを貼り付けます

public class JAXBExample {
    public static void main(String[] args) {

     try {

        File file = new File("GeoLocation.xml");
        JAXBContext jaxbContext = JAXBContext.newInstance(GeocodeResponse.class);//(GeocodeResponse.class);

        Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();
        GeocodeResponse latLong = (GeocodeResponse) jaxbUnmarshaller.unmarshal(file);

        System.out.println(latLong);
//      System.out.println(latLong.getLatitude()+ ", "+latLong.getLongitude());

      } catch (JAXBException e) {
        e.printStackTrace();
      }

    }
}
