1. 예매2단계 ReserveTwo 화면

2. 주요기능

-1) Servlet 단계

1. 지역식별번호, 영화관식별번호를 가져옴 (Controller)

2. 지정된 날짜가 없을 경우, 오늘날짜를 사용 (Controller)

3. lineUp(순서변경용 식별번호)에 따라 영화제목 값을 가져옴 (Repository)

	public List<Movie> selectScreen(Connection conn, String theaterNo, String screenDate, String lineUp) {
	List<Movie> list = new ArrayList<>();
	PreparedStatement pstmt = null;
	ResultSet rset = null;
	String sql = prop.getProperty("selectS");
	sql += " ORDER BY " + screenOrderBy(lineUp);
	try {
	pstmt = conn.prepareStatement(sql);
	pstmt.setString(1, theaterNo);
	pstmt.setString(2, screenDate);
	rset = pstmt.executeQuery();
	while(rset.next()) {
	list.add(new Movie(rset.getInt("MOVIE_NO"), rset.getString("TITLE"), rset.getInt("AGE_LIMIT")));
	}
	} catch (SQLException e) {
	e.printStackTrace();
	} finally {
	close(rset);
	close(pstmt);
	}
	return list;
	}

-2) View 단계

1. 현재 상영중인 영화제목 리스트 나열

2. 영화제목 순서를 lineUp 번호에 따라 최신순/이름순/나이제한순 으로 변경가능 (동기식)

	<div id="choose_movie" class="threediv">
	<div class="title">영화선택</div>
	<select name="lineUp" style="width: 100px;" onchange="changeLineUp(this);">
	<option value="4" ${empty param.lineUp or param.lineUp eq '4' ? 'selected="selected"' : ''}>최신순</option>
	<option value="2" ${param.lineUp eq '2' ? 'selected="selected"' : ''}>이름순</option>
	<option value="3" ${param.lineUp eq '3' ? 'selected="selected"' : ''}>나이제한순</option>
	</select>
	<ul>
	<c:forEach items="${movieList}" var="m">
	<input type="hidden" name="sectionNo" value="${param.sectionNo}"/>
	<input type="hidden" name="theaterNo" value="${param.theaterNo}"/>
	<li><a href="#selectMovie" onclick="selectMovie('${m.movieNo}')">
	<span class="grade_${m.ageLimit}">${m.ageLimit==0 ? 'All':m.ageLimit}</span>
	<strong>${m.title}</strong></a></li>
	</c:forEach>
	</ul>
	</div>

3. 배운점

- null 값 확인, 혹은 Integer파싱하기, 오늘 날짜(new Date())를 가져오거나 날짜포맷지정하기처럼 자주사용하는 메서드는 따로 빼내어 놓기!

- 재사용성 UP + 관리용이 !
