안녕하세요. 자바 변수와, 객체, 메소드 관련해서 정리를 하고 있는데 제가 정리를 하는게 너무 미숙해서
고수님들께 도움을 청하려고 질문을 올렸습니다.
3가지의 클래스 파일이 있는데, 이 3가지의 구조 변수와 메소드, 객체를 각 클래스별로 정리하고
어떻게 서로 작동을 하는지에 대해서 나눠서 서로간의 관계를 나타내는 작업을 하고 있는데 좀 처럼
쉽게 되는거 같지않아서 질문을 올렸습니다.
제가 나름 정말 열심히 40분동안 그렸다지웠다하면서 한글파일에서 표로 정리한건데 아래의 도식화
해놓은 것이 그림 아래의 3개의 소스파일을 분석한것과 맞는지 궁금합니다 ㅠㅠ..
클래스는 빨간색으로 칠한 3개의 클래스 DotCombust와 Dotcom , Gamehelper가 있습니다.
메소드 안에 있는 객체와 변수들도 정리를 해주어야 하는데 어떻게 정리를 해줘야 효과적일지
고민입니다ㅠㅠ
