내 수업 프로젝트 용 자바 클래스를 작성했으며 모든 메소드가 무효이며 기본적으로 아무 것도하지 않고 내 기본 메소드에서 메소드를 호출합니다.코드를보다 융통성있게 만드는 방법
이 코드는 기본적으로 학생이 월세를 임대료 및 대출 지불과 관련하여 관리하는 데 도움이됩니다.
어떤 사람이 잘못된 방향으로 올바른 방향으로 나를 가리킬 수 있습니까? 일반적으로 코딩 습관에 대한 조언이 있습니까?

Andrei는 OO 패러다임 및 커뮤니티 관측 코딩 표준에 따라 그의 접근 방식이 수용 가능하다고 생각하지 않는다고 말합니다. – Joel
정확히 Joel. 나는 경험이 많은 사용자로부터 어떻게해야하는지에 대한 의견을 얻고 싶습니다. 하지만이 문제는 책이 클래스와 메소드를 다시 방문하는 현재 장의 2 장에서 해결 될 것이라고 생각합니다. 그러나 여전히 코드를 좀 더 유연하게 만드는 방법을 알고 싶습니다. –
