構文エラー "}"を入力してクラスブロックを完成させよう

Question

私は友達のためのプログラムを作っています。書き込みを作成してテキストを.txtファイルに保存しようとすると、エラーが発生しました。 Java Swingで何かを作成したのは初めてです。

エラーにはアスタリスクが付きます。

あなただけのこの声明の中で}を追加するのを忘れ：

catch (IOException e) { 
    e.printStackTrace(); 
} 

アンドリュー・トンプソンが言ったのと同じように：簡単なインデントが適切に行われた場合に見つけることが、このエラーは非常に簡単に作られているだろう、と共通として使用する必要があります練習。
