if (temp === 0) {
mainString = mainString + "{key:\"" + "${stdn.key}" + "\",name:\"" + "${stdn.value.name}" + "\",rollno:\"" + "${stdn.value.rollNo}" + "\",marks:\"" + "${stdn.value.marks}" + "\"}";
} else {
mainString = mainString + "{key:\"" + "${stdn.key}" + "\",name:\"" + "${stdn.value.name}" + "\",rollno:\"" + "${stdn.value.rollNo}" + "\",marks:\"" + "${stdn.value.marks}" + "\"},";

<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
<html>
<head>
<title><c:forEach>YOUR CODE </title>
</head>
<body>
<c:forEach var="i" begin="1" end="5">
NAME <c:out value="${i}"/><p>
</c:forEach>
</body>
</html>
This would produce following result:
这将产生以下结果：
NAME 1
NAME 2
NAME 3
NAME 4
NAME 5
Above is simplest example.. following is with items var
以上是最简单的例子..以下是项目变量
<table>
<c:forEach var="student" items="${person.person}" varStatus="counter">
<c:choose>
<c:when test="${counter.count % 2 == 0}">
<c:set var="rowStyle" scope="page" value="odd"/>
</c:when>
<c:otherwise>
<c:set var="rowStyle" scope="page" value="even"/>
</c:otherwise>
</c:choose>
<tr class="??${rowStyle}">
<td>${student.name}</td>
<td>${student.age}</td>
<td>${student.height}</td>
</tr>
</c:forEach>
</table>
this way you can use the <c:forEach> </c:forEach>TAG..
这样你就可以使用 <c:forEach> </c:forEach>TAG..
If you have any specific problem then please explain
