안녕하세요. 기본적인 질문입니다. 내 코드에서는 생성자에서 GUI를 만들고 버튼 변경을 처리하기 위해 ActionListener 클래스를 중첩합니다. 이 코드는 gui를 생성하고 action listener는 actionPerformed 메소드를 통해 올바르게 실행됩니다. 그러나, GUI의 패널을 변경하는 여러 가지 방법을 시도했지만 프로그램을 설정 한 것처럼 느껴집니다. 작동하지 않을 수 있습니다. 죄송합니다. 반복이지만 S.O.에서 잠시 동안 검색 한 후. 나는 내 문제에 도움이 될 좋은 모범을 발견하지 못했습니다.JPanel을 다른 JPanel로 바꾸기
