こんにちは、私の機能（特定の色のジオメトリのコレクション）をペイントしようとしていますが、このエラーが発生します：キャストされる配列リストに問題がありますが、修正する方法がありませんPLZは私を助けてくれます事前に感謝します

ここで彼は例外を取得します：

Color color = Color.yellow;
Stroke stroke =new BasicStroke(5, BasicStroke.CAP_ROUND,BasicStroke.JOIN_ROUND);

//この行で：
paintGeometryCollection((GeometryCollection) selectedFeatures(),
graphics, viewport, true,
stroke,fillPaint, true,
stroke, color);
そして、これが必要な他の方法です：

ArrayList selectedFeatures = new ArrayList();

selectedFeatures.add(search().getGeometry());
// search() is a BasicFeature
}
return selectedFeatures;
