Ich bekomme diesen Fehler, wenn ich versuche, den Wert kincaid einer Java-Datei zu erhalten. Ich konnte nicht finden, was ich tun sollte. Wie ich verstehe, ist es ein Problem beim Schließen einer Datei. Ich habe eine andere Optionen zum Lesen-Closin versucht, aber ich konnte nicht tun. Wie sollte ich die Closin Operation machen? Danke.bufferedReader eine Datei schließen
