Siring - simple question of a newbie

Question

I am a jsp newbie. I try a little code as follows:
<% String a1="welcome to";
String a2="\n";
String a3="this test";
String a=a1+a2+a3;%>
<br>
Print out result a=
<%=a%>;
Then it prints a=welcome to this test.
I want to see like this:
welcome to
this test (with a line break).
But dont know why a does not show up like that.
Please help. Thanks.

Answer 1

Yes, however, my purpose is to create a text from several texts. I do not print that text out. Instead, I will write it into a body of a message to be sent by email.
For instance, I use a form HTML to ask users to enter their "name" and "address". Then that form points to a jsp. The jsp then creates a text=name +"\n"+address then it calls a java class to send email. In the received email, I expect to see this, for example:
Peter Richardson.
123 East Street.
Unfortunately, I still see this: Peter Richardson 123 Eas Street.
So please help. Thanks.
