Book_DTO

data transfer object

package hb.net.jave_20151210; import java.util.ArrayList; import java.util.Iterator; public class Book_DTO { ArrayList <String> name = new ArrayList(); String name2; String name3; Iterator iter = name.iterator(); public void setName(ArrayList<String> name){ this.name = name; } public String getName(){ for(int i = 0 ; i<name.size();i++){ name2 = name.get(i); } return name2+"\n"; } }

기본실행화면

textarea랑 field에 "검색어를 입력해주세요"를 focus이벤트로 처리했다.

나머지 버튼은 그냥 화면이동 

검색버튼은 미구현 시간없어 ㅠㅠ

여기서 books DTO랑 상호작용을 한다. 추가 삭제 구현은 아직 못함

대충 개념만 알아두길.

이건 14일차에서 하던거 불러오는거 (회원등록)

* 중요한건 swing 사용법과 Layout 정리 정도?

* 그리고 가장 핵심은 DTO 이다. 저런 방식을 잘 기억해두자.

* 로직짤 때 use_case잘 생각해보자
