Your problem is that the Collection that the setTo() method expects is a
Collection of javax.mail.internet.InternetAddress, not a collection of
String.  The Jakarta Commons e-mail package builds onto the javax.mail
package, so you need to download that, then using:

    import javax.mail.internet.InternetAddress;

replace your:

    String add = "add@yahoo.com";
    String add2 = "add2@yahoo.com";

with:

    InternetAddress add = new InternetAddress("add@yahoo.com");
    InternetAddress add2 = new InternetAddress("add2@yahoo.com");

and away you go!

Mainly, this scenario.  Let's say you want to find a piece of
information in a large text file.  You read the entire text file into a
String, then find the information and use substring(...) to extract it
from the orginal String.  There's a problem now.  The resulting String
object looks like it's just a few characters long, but it's really
pointing behind the scenes to the ENTIRE orginal String that was read
from the text file.  The original String actually shares data with its
substring.  That's meant as an optimization, but if you intend to
discard the original String and keep the tiny subset, it can keep a lot
of garbage in memory.

The solution is to use new String.  The String constructor that takes
another String as a parameter will actually copy not just the String
object, but also the underlying char array that it points to.  Now the
old really long String can be garbage collected, and you're only using a
small amount of memory for the tiny information you've extracted from
the file.

As I said, it's a little arcance, but it's there.
