And how is this any different from using "if (user.equals("admin"))"?

You need to do some basic Java study.
The conditional test above actually asks this:
If
the explicit String type object reference 'user' points to the same
Note for newer Java programmers:
For this example, they are equivalent. But String.compareTo() returns an int
and can be used, like the C function memcmp(), to test all of >, ==, and <.
In addition to String.equals(), do not overlook String.equalsIngoreCase(),
should you need a case-insensit

Hi I am getting a form field (POSTed form) as
String user = (String) request.getParameter("user");
When I out.print this, it writes the correct value, but when i COMPARE this
in an IF condition, it doesnt work. Any reason why? For example, lets say
the "user" textfield in my form is "admin".
