GUI 작성 방법을 배우고 있으며, actionListeners를 이해하는 데 도움이 필요합니다. 모든 것은 코드화되어 있습니다. 그러나 어떤 이유로 인해 Calculate Button은 실제로 메인 윈도우의 결과와 함께 새로운 윈도우를 열지 않습니다. 이 프로그램은 샌드위치 가게로 샌드위치를 만들고 음료를 선택할 수 있습니다. 사용자가 완료되면 계산을 클릭하고 다른 종료 버튼과 함께 소계, 세금 및 최종 합계가 표시된 새 창을 여는 것으로 가정합니다. 지금까지 제가 가지고있는 모든 코드가 있습니다. 누구든지 제공 할 수있는 지침을 주시면 감사하겠습니다.동작 수신기 결과가 새 창이 열림

정말 고마워요, 그게 그렇게 단순한 것이 었습니다. 나는 왜 그것이 작동하지 않는지 알아 내려고 노력하면서이 문제를 디버깅 해왔다. 감사합니다. –
도와 드릴 수있어서 기쁩니다! 나는 이것도 바보 같은 실수를 많이 겪었습니다 :) – Adrian
