각 기능에 대한 예외사항과 핸들링도 기재되면 좋을 것 같습니다!

3, 1, 9와 같은 숫자를 상수로 선언해 사용하시는건 어떨까요?

출력과 boolean값 return을 동시에 해서 두가지 일을 하는 것 처럼 보입니다
외부에서 ture/false에 따라 출력 여부를 결정하도록 변경하면 어떨까요?

의도는 generateAnswer()에서 answer에 값을 넣어주는 부분이 있는데,
int 자료형이면 값 참조를 못해서, 값이 안들어갈까봐 Integer로 설정해주었습니다!
그런데, 찾아보니까 int여도 값이 잘 들어간다고 하네요ㅠ
int로 바꾸는게 더 좋을 것 같습니다.
