如果使用jsp scriplet，如何从单选按钮获取值

我有一个带有单选按钮的表单，其值是从数据库中获取的。下面是我表格中的代码。顺便说一句，这张表格是用于调查问题的

for(int i=0; i<qlist.size(); i++){
//question loop
for(int j=0; j<alist.size(); j++){
//answer loop
    <input type="radio" name="radio_<%=j%>" value="<%= alist.getAnswerDesc()%>"
    <input type="radio" name="radio_<%=j%>" value="<%= alist.getAnswerDesc()%>"
    }
}

---

for（int i=0；i此示例代码将从数据库中提取值到单选按钮值

<%
// add code for connection here

Statement stmt = connect.createStatement();
ResultSet Rs = null;
Rs = stmt.executeQuery("Select column_name from table_name ");
int i=1;%>
<%while(Rs.next()){
%>

<tr><td><input type="radio" value="<%=Rs.getString("column_name")%>" name="radio<%=i%>"/><%=Rs.getString("column_name")%></td></tr>
<%
i++;
}
%>

您有单选按钮的名称吗？？
<%
// add code for connection here

Statement stmt = connect.createStatement();
ResultSet Rs = null;
Rs = stmt.executeQuery("Select column_name from table_name ");
int i=1;%>
<%while(Rs.next()){
%>

<tr><td><input type="radio" value="<%=Rs.getString("column_name")%>" name="radio<%=i%>"/><%=Rs.getString("column_name")%></td></tr>
<%
i++;
}
%>
