try(MyFileWriter writer2 = new MyFileWriter()){ writer2.write("빵이 먹고 싶어요."); } catch (Exception e){ e.printStackTrace(); }이런 경우에 close()함수가 실행된다고 하셨는데요.AutoCloseable이 아닌 인터페이스를 구현한 class인 경우에도,try구문에 소괄호로 객체를 생성했을때 해당 인터페이스에 있는 메소드를 호출하나요?

영상에서는 @SpringBootTest 보다 단위테스트가 중요하다고 말씀하셨는데.. 실제 프로젝트에서는 그럼 Fake객체를 생각해 볼 수 있다고 생각됩니다.Fake객체를 사용하게 되면 Application Layer처럼 여러 객체들이 맞물려서 동작하는 과정에서 제대로 테스트를 했다고 볼 수 있나? 라는 의문이 드는데.. 영한님은 어떻게 생각하시는지 궁금합니다. AI의 답변 보다는 영한님의 개인적인 의견을 들어보고 싶습니다..!

val values = fruits.filter { fruit -> fruit.name == "사과" } .mapNotNull { fruit -> fruit.nullOrValue() } nullable한 List에서 null이 아닌 element만 가지고 오는 mapNotNull중에서.. nullOrValue()는 임의로 만드신 확장함수인가요?

static class TestBean에서 @Autowired를 3개를 했지만 3개가 등록이 되는건 아니라고 하셨는데 위에서 저렇게 print를 했을때에는 나오지 않더라구요... 어떻게 해야지 밑에 @Autowired중에 잘 들어간 함수들을 출력해서 직접 볼 수 있을지가 궁금합니다.해당 코드를 실행했을 때의 결과는 다음과 같습니다.

 org.junit.runners.model.InvalidTestClassError: Invalid test class 'hello.core.member.MemberServiceTest': 1. Method join() should be public 영한님 코드랑 동일한데 해당 에러가 발생합니다.에러 메시지처럼 join() 에 public 을 붙여 줬더니 해결이 되었는데, 이유가 뭘까요?

(예/아니오)네3. 질문 잘하기 메뉴얼을 읽어보셨나요? (예/아니오) 네[질문 내용]안녕하세요? 생성자 주입에 대해서 질문이 있습니다. 앞서서 영한님의 강의에서, bean을 통해서 역할과 책임을 구분한다는 이야기를 많이 해주셨습니다.app config에서 배우를 정하고, 각 클래스들은 그냥 자신의 역할에만 집중한다는 비유를 들어서 말씀해주셨는데요생성자를 직접 주입하는 방식은 사실 기존의 말씀과 상반되는 내용같아서, 제가 제대로 이해한 게 맞는지 싶어서 질문드립니다. 비유를 사용하여 그대로 말씀을 드리자면, '불변, 필수'의 관계에서는 앞서 말씀과 다르긴하지만, 생성자 주입을 통해 그냥 하나의 클래스에서 배우도 정하고 역할도 스스로 하는 게 맞을까요?추가로, 만약 생성자를 주입해주는 방식만 사용한다고 하면, (싱글톤이라는 기능을 제외할 때)사실 빈을 왜 사용하는지?도 의문이 자연스럽게 듭니다..!
