jtextfield Cursor blinkt zu schnell und registriert keine Eingabe zu Zeiten

Question

Hallo Ich bin ein Programm erstellen, wo der Benutzer bestimmte Eingaben geben muss, um Punkte zu erhalten und es gibt einen Timer, aber der Timer ist ich erstellt wird den Cursor im jtextfield zu schnell blinken, damit das Programm zeitweise Eingaben macht. In meiner Timer-Klasse habe ich TimerTask importiert und timer.scheduleAtFixedRate() verwendet, um die Zeit zu zählen. Das ist nicht alles mein Code, aber das ist die Hauptklasse.

Answer 1

Ich verstehe nicht, wo diese timer herkommt? Sie können diesen Code verwenden Timer timer = new Timer(1000,this); anstelle von timer timer = new timer(60);

1000 aktivieren, um Sie mit echtem Timer zu verwenden.

Ich hoffe, dass dies das Leben ein wenig leichter machen wird.
