私が取り組んでいる課題では、クラス、メソッド、カプセル化などを使用せずに数独ゲームを作成する必要があります。ユーザーが「fourArray」または「nineArray」に入力した値に重複値が含まれていないことを検証するのに問題があります。これまでのところ、いずれかの配列の列と行の両方を反復処理するために、ネストされた for ループを使用しようとしました。たとえば、重複する値があるかどうかを判断するために、プログラムの最後に次のコードを含めようとしています。
for (int i = 0; i < fourArray.length; i++) {
for (int j = i + 1; j < fourArray.length; j++)
if (fourArray[i] == fourArray[j]) {
System.out.println("No Sudoku");
} else {
System.out.println("Sudoku!);
}
}
ただし、これは機能していません。配列を反復処理して重複する値を見つけ、何もない場合は「数独!」と出力します。重複する値がある場合は、「Sudoku!」を出力したいと思います。配列をソートする必要はありますか? または、私が気付いていない方法がありますか？私は自分のプログラムを含めました。お時間をいただきありがとうございます。
