メインメソッド全体で申し訳ありません。私は Java があまり得意ではないので、自分の状況をどのように説明したらよいかわかりません。

ArrayList配列の代わりに を使用し、次の方法で複数の項目を追加しaddAllます。

追加したいアイテムがまだコレクションにない場合は、最初にコレクションに入れます。

mylist.addAll(Arrays.asList(1, 2, 3));

または、一度に 1 つずつ追加できます。

mylist.add(1);
mylist.add(2);
mylist.add(3);

免責事項：私はあなたのコードを読みたくなかったので、あなたのコードを閲覧しただけです。私は主にあなたの質問のタイトルに基づいて答えています。
