ANOTHER IndexOutofBounds例外

Question

よしは、（...今日... Javaで）私の問題のほとんどを通じて得た

、私は、私の質問をステップ私の値を取得するために管理し...しかし用何らかの理由で、ループのすべての反復中に範囲外の例外がスローされています...実際にはプログラムの終了や何かを引き起こしていませんが、私は質問を通してページを呼び出し、応答を返します。最後の質問が尋ねられるまでループの各カウントのエラー。 インデックスカウンタがリストのサイズのときに実行されるcalcPersonnelRisk（）をコメントアウトすると、ANYエラーのない質問が実行されます。なぜなら、そのメソッドは自分の答えから値を私の変数に代入するだけで、そのコードを持っているのはどうしてこんなことになるのか分からないからです。私はプログラマーとしてまだ初期段階にあり、効率的にデバッグする能力を開発しています...しかし、一見してどんな入力も感謝しています。前もって感謝します！

は申し訳ありませんが私はそれを簡単に見てましたが、私は[はい]ボタンを何が起こっているかを理解していれば...アクションの魔女が質問リストをクリアしgetAnswerは魔女がそう質問リストから値を取得しようと呼び出すトリガー
