Assemble a product table as a java jsp showcase

Question

I’m having a hard time presenting a showcase product list using Java and JSP.

I can get the data, but I don’t know how to fill this table using the <c:forEach>

My table would have this structure:

<table>
    <c:forEach items="${produtos}" var="p">
        <tr>
            <td> ${p.nome } </td> <td>${p.nome } </td> <td>${p.nome }</td>
        </tr>
    </c:forEach>
</table>

But what is displayed is:

**produto 1 produto 1 produto 1**
**produto 2 produto 2 produto 2**
**produto 3 produto 3 produto 3**

I wanted you to show off like this:

**produto 1 produto 2 produto 3**
**produto 4 produto 5 produto 6**

Answer 1

To write from 3 to 3 products you can do something in this sense:

Use an accountant varStatus, for example contador, to find out what the forEach, this way every time contador.count is divisible by 3 you close the current row and add a new row in the table.

<table>
    <c:forEach items="${produtos}" var="p" varStatus="contador">
        <tr>
            <td> ${p.nome } </td>
        <c:if test="${contador.count % 3}">
        </tr>
        <tr>
        </c:if>
    </c:forEach>
</table>

In the end you can end up with a <tr> further, leaving your HTML inconsistent, to resolve this situation make a check c:if before writing the new <tr>, You should check if the counter is smaller than the list size. As I don’t know if you are using array or list you can check the size with .length() and .size() respectively.
