java - カレンダーの日付と 2 つの日付の間隔の配列の同等性に基づくラベルの可視性

Question

カレンダーから選んだ日付に基づいてラベルを表示しようとしています。開始日と終了日はデータベースから取得され、それらの間の日付は計算されています..すべて正常に機能しています..しかし、カレンダーの日付ピッキングで間隔が等しいかどうかを確認しても、可視性が得られません..助けてください..これが私のものですコード

if(lb[m].equals(d.setPickedDate()))

おそらく次のようになります。

if(lb[k][m].equals(d.setPickedDate()))

編集：さらに調べてみると、これはありそうにないように思えます（... d.setPickedDate()a を返さない限りJTextField）。比較する実際のオブジェクトを比較していること、およびそれらが同じクラスのインスタンスであることを確認してください。
