@FunctionalInterface 어노테이션을 명세하는 것과 하지 않는 것에는 어떤 차이가 있을까요?

과정(Course)은 기수 단위로 운영하며, 여러 개의 강의(Session)를 가질 수 있다.
요구사항 속 기수는 하나의 과정에서 생성되는 N 개의 강의를 나타내는 걸로 보이네요. 😄
- 과정: TDD, 클린 코드 with Java
- 강의: TDD, 클린 코드 with Java 19기
- 강의: TDD, 클린 코드 with Java 18기

처음 Session 이 생성될 때부터 유/무료가 나뉠 수 있도록 팩터리 메서드를 제공하는 것도 방법일거 같네요 😄

유료 강의의 경우 결제는 이미 완료한 것으로 가정하고 이후 과정을 구현한다.
결제를 완료한 결제 정보는 payments 모듈을 통해 관리되며, 결제 정보는 Payment 객체에 담겨 반한된다.
이 내용이 무슨말인지 몰라 구현을 하진 못했습니다.
