JSP Request Object

When I call request.getParameter to get the value of a field from the calling page, if that field was blank then is the string returned "" (empty)? I am using a conditional like
if(name != "" && email != "") and even if I leave the fields blank it still enters the if and never sees the else. Why?

I always check for null and the length of the returned parameter. What is returned (null or "") depends on the browser.
EX:
if( (email != null) && (email.length() != 0) )

I am using the .equals method and it is working now.
Thanks
