이 코딩을 도와 주시겠습니까? 특정 작업을 실행하는 타이머이지만 멈추지 않습니다! java.swing.Timer 및 WebLookAndFeel을 사용하고 있습니다 (NotificationManager : WebLaF에 속함). <timer>.stop();
자체 내부에 전화를 시도했지만 인스턴스화되지 않는다고 말합니다. 또한 <timer>.setRepeats(false)
을 추가하여 NPE를 시도했습니다. <timer>
은 각 고유 한 타이머를 나타냅니다.java.swing.Timer가 중지되지 않음
타이머가없는 코딩은 완벽하게 작동하지만 최근에 앱을 추가하면 타이머를 사용해야했습니다.
필자는 코딩에서 내가 사용한 것을 대부분 가르쳐 주었기 때문에 타이머를 디버깅하는 데별로 좋지 않았습니다. 나와 함께 견뎌주세요.

고마워. 나는 쓸모없는 정보를 제거함으로써 가능한 한이 게시물을 짧게 유지하기 위해 catch 블록을 비 웠습니다. 감사합니다. 방금 evt.getSource에()를 추가하여 답변을 업데이트했습니다. –
@JohanBrink : 정정 해 주셔서 감사합니다! –
