私はこのプロセスで激しく憤慨しています。私の家庭教師は私の電話に1週間以上応答していません。これが私の最後の試みです。私は2つのことの他にすべてのコードを扱っています。 1.私の配列で検索することができますが、私は最初の正解を得るだけです。すべてのヒットをコンソールに戻したいと思います。 2.バブルソートで例外エラーが発生し、私は何をしているのか分かりません。私は1次元の整数をすべてうまく埋め込んだ配列をソートすることができます。配列を検索しても機能しない配列を検索することはできません
私の問題は、ある次元から複数の次元に向かう配列の遷移を扱うことができないということです。私は 'for（int i = 0; i < bottleCount（）; i ++）'を 'foreach（ボトル内のvarボトル）'を選択することの意味を理解していません。私がお金を追加したいのであれば、私は最初の方が良いと思います。しかし、私は配列からいくつかの答えを出したいときにforeachは使用するツールではありません。 bottles.xyzが動作している時もありますが、bottleS.xyzが動作している時もあります。
私はノブであり、ほとんどが本を読んで自己学習していることをご理解ください。私はもっと学ぶためにWebクラスを取っていますが、私の先生は役に立たず、理解しようとするうちに私は涙に不満です。私はかなり近いと信じていますが、細かい点を理解する必要はありません。先生はToStringを使って何とか私の検索を取得し、私のsodacrateを泡立てなければならないことを示しています。私は実際に私のキットを私のアレイと一緒に適切に得る方法を実際に学ぶ傾向があります。私は完全に私を逃すToStringソリューションを受け入れることができないことに失敗しました。
すべての作業コードを一番下に置き、Run（）からメニューを削除してテストを効率化しました。誰かが私を助けることができれば私は感謝しなければならない私は私の仕事を私のメニューが復活した状態で手渡すでしょう。私は理解し、学びたいと思っています。
