java - 我怎样才能从这个表中在jsp中做出正确的问答？

Question

我想从 oracle 数据库生成问题和答案，并按照客观问题的正确问题和答案对它们进行排序？

Controller 代码

public ArrayList<DOWNLOAD_SUB> getQUESTION_SUB2() throws SQLException{
                ArrayList<DOWNLOAD_SUB> question_subssss = new ArrayList<>();

                Connection connection = fACADE.getConnection();
                PreparedStatement ps = connection.prepareStatement("SELECT A.QUESTION, B.ANSWER FROM QUESTION_OBJ A, OBJ_ANSWER B WHERE A.QUESTION_OBJ_ID = B.QUESTION_OBJ_ID");
                ResultSet rs = ps.executeQuery();

                while(rs.next()){

                    DOWNLOAD_SUB question_sub1=new DOWNLOAD_SUB();

                    question_sub1.setQUESTION(rs.getString(1));
                    question_sub1.setANSWER(rs.getString(2));
                    System.out.println(rs.getString(1));

                    question_subssss.add(question_sub1);

                }
                return question_subssss;

            }

jsp 文件 - 这是重复相同问题的普通表格，我不知道如何在不使用此表格的情况下进行正确的问答

<table class="table" border=2 bgcolor="white">
            <thead>
                <tr>
                <th>QUESTION</th>
                <th>AWNSER</th>


                </tr>
            </thead>
            <tbody>
                <%
                            for (DOWNLOAD_SUB fquestion_sub : DOWNLOAD_SUB2) 
                            {
                        %>

                <tr>

                    <td><%=fquestion_sub.getQUESTION()%></td>
                    <td><%=fquestion_sub.getANSWER()%></td>

                </tr>


                <%
                            }
                        %>

结果是

           QUESTION                                             |ANSWER
WHAT ARE THE MOLECULE STATE THAT OCCUR DURING HIGH PRESSURE?    |IRON
WHAT ARE THE MOLECULE STATE THAT OCCUR DURING HIGH PRESSURE?    |GAS STATE
WHAT ARE THE MOLECULE STATE THAT OCCUR DURING HIGH PRESSURE?    |LIQUID
WHAT ARE THE MOLECULE STATE THAT OCCUR DURING HIGH PRESSURE?    |SOLID

我需要的是

 1)WHAT ARE THE MOLECULE STATE THAT OCCUR DURING HIGH PRESSURE?

 A. IRON
 B. GAS STATE
 C. LIQUID
 D. SOLID

Answer 1

假设 DOWNLOAD_SUB2 是单题多选

<%=DOWNLOAD_SUB2.get(0).getQUESTION()%>
<ol type="A">
<%    for (DOWNLOAD_SUB fquestion_sub : DOWNLOAD_SUB2)  {  %>
   <li><%=fquestion_sub.getANSWER()%></li>
<% } %>
</ol>

您可以使用有序列表标签 <ol>，而不是使用 HTML 表格标签。和<li>

理想情况下，您的数据结构应该是 Map<String, List<String>>其中Map中的key是问题，list是多项选择。
