kolon2:1.25,1.14,1.10..

次に、それらを小さいものから大きいものへと並べ替えました。

置き換えられた番号があります。番号を置き換えたくありません。たとえば、テキストに 3,3,3,3,3,2,2,2,2,1,1,1,1,1,1 が含まれている場合

見てみましょうTreeSet：

TreeMap に基づく NavigableSet 実装。要素は、使用されるコンストラクターに応じて、自然順序付けを使用するか、セットの作成時に提供される Comparator によって順序付けられます。

これにより、各要素が 1 つだけ存在し、必要に応じてリストがソートされていることが確認されます。

これを試してみてください。すべての行で重複する値が見つかり、各行も私にとってはうまくいきます:)
