디자인패턴을 이용하면 내용의 변경이 있을 때, 손쉽게 변경이 가능하다

첨부한 파일중 OOP4, OOP5, OOP6(현재 올린 글의 내용과 똑같음)을 보면

OOP4와 OOP5는 재사용에서 매우 떨어진다는 것을 확인할 수 있을 것이다.

OOP4.zip

OOP5.zip

OOP6.zip

첨부파일 사용법은 압축을 풀고

Eclipse -> File -> Import -> General -> Existing Projects into Workspace -> Select root directory 에서 Browser -> 압축 푼 폴더 클릭하면 됩니다
