私は.javaファイルを持っています。それは完全に実行されます。.jar ファイルに変換します。次に、「exe4j」という名前のプログラムを使用して.exeファイルに変換しようとしましたが、正常に変換されました。しかし、この .exe ファイルを開くと、次のエラー メッセージが表示されます。
java.util.NoSuchElementException
at java.util.Scanner.throwFor(Unknown Source)
at java.util.Scanner.next(Unknown Source)
at penghitung.persentase(programguru.java:27)

どういう意味ですか?.java ファイルが完全に実行されるため、混乱しています。
これが私のコードです:
