JSP syntactical error in scripting

Question

I don't understand why the first program in JSP is working, but the second program is giving an error:

<% for(int i=0;i<10;i++){

out.print("hello");
}
%>


<% for(int i=0;i<10;i++){

<%= "hello" %>
}
%>

Answer 1

Try it like this:

<% for(int i=0;i<10;i++){
out.print("hello");
}
%>

<% for(int i=0;i<10;i++){ %>
<%= "hello" %>
<%
}
%>

Answer 2

At a guess, it is because you can't nest '%<' tags.
