初心者の質問に申し訳ありませんが、私はこれを理解できません。このコードの開始時に、私は不正な式の開始エラーを受けています。なぜその理由が分かりません。どんな助けもありがとうございます。ここで 不正な式の開始public int getInput

Scanner input = new Scanner(System.in);
choice = input.nextInt();
if(choice > length){
System.out.println("The number is out of the array bound");

方法自体は範囲内のどこかで宣言されているchoice' 'と仮定し、罰金です。クラスの外のように違法に定義されているか、別のメソッドの中に定義されている可能性がありますが、それを囲むコードを見ずに言うことは不可能です。 – azurefrog
