Try below:

Index.html file:

<form action = "test.jsp">

<input type = "text" name = "userId" value = "" />
<input type = "text" name = "age" value = ""/>
<input type = "submit" name = "submit" value = "Click Here"/>

</form>

test.jsp file:

<%
String userId = request.getParameter("userId");
String age = request.getParameter("age");
int agge = 0;
if(age != null)
{
try
{
agge = Integer.parseInt("age");
}
catch(NumberFormatException e)
{
// age should be intered in number
}
}

if(agge >= 20)
{
%><%@include file = "above20.jsp"%><%
}
else
{
%><%@include file = "below20.jsp"%><%
}
%>
