[FIXED] Get the most recent data from database to jsp page

Issue

I'm trying to get data from the last 5 days from mysql database using servlet and jsp. I created a database class where it looks for the date between the last 5 days until the current date. Then on my serlvet, I called that method and store the values in a list and forward it the jsp page. I created a table in the jsp page to display the database data, but nothing is showing up. I debugged it and it was showing the list was empty. I am not sure what I am doing wrong. Here is my code:

Database method:

public static List getMaxRecordsHomePage(int id) {
    List recordList = new ArrayList<>();

    DateFormat dateFormat = new SimpleDateFormat("yyyy/MM/dd");
    Date date = new Date();
    String currentDate = dateFormat.format(date);

    Calendar cal = Calendar.getInstance();
    cal.add(Calendar.DATE, -5);
    Date previousDate = cal.getTime();
    String fromDate = dateFormat.format(previousDate);

    try {
        Connection conn = DBConnection.getConnection();
        String query = "SELECT * FROM record WHERE userId=? AND date BETWEEN ? AND ?";
        PreparedStatement stmt = conn.prepareStatement(query);
        stmt.setInt(1, id);
        stmt.setString(2, fromDate);
        stmt.setString(3, currentDate);
        ResultSet rs = stmt.executeQuery();

        while(rs.next()) {
            Record records = new Record();
            records.setId(id);
            records.setCategory(rs.getString("category"));
            records.setDescription(rs.getString("description"));
            records.setAmount(rs.getString("amount"));
            records.setDate(rs.getString("date"));
            recordList.add(records);
        }   
    } catch (Exception e) {
        System.out.println(e);
    }
    return recordList;
    }
}

Serlvet:

protected void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException
{
    int id = SessionService.getSessionId(request, response);                    
    List recordList = FinanceService.getMaxRecordsHomePage(id);
    request.setAttribute("recordList", recordList);

    RouteService.routeDispatcher(request, response, "homepage.jsp");
}

JSP page:

<table>
    <caption>Recent Records</caption>
    <tr>
        <td>Category</td>
        <td>Short Description</td>
        <td>Amount</td>
        <td>Date</td>
    </tr>
    <c:forEach var="Records" items="${recordList}">
        <tr>
            <td><c:out value="${Records.category}"/></td>
            <td><c:out value="${Records.description}"/></td>
            <td>$<c:out value="${Records.amount}"/></td>
            <td><c:out value="${Records.date}"/></td>
        </tr>
    </c:forEach>
</table>

Solution

The BETWEEN operator selects values within a range. The values can be numbers, text, or dates.

If you want to get date within a range, you can choose the column type as 'data', 'datetime' etc. in database.
