シンプルなプログラムで作業していて、同じ問題が引き続き発生します。それはinput.close();の中でcloseという単語に下線を引いています。私は自分のプログラムを検索してエラーを見つけようとしますが、役に立たないのです。私のコードは以下の通りです：トークン "close"の構文エラー、このトークンの後に必要な識別子

おかげさまで、ありがとうございました！クラスの終わりに
正しくインデントすると、その行がメソッド内にないことがわかります。 –
あなたのクラス宣言はどこですか？ – shmosel
ファイルの最後のinput.close（）はメソッドから外れています。 – alpert
