While this is really a Java question and not a JSP issue it does give me a
chance to expound one of my favorite programming points. You should always
create code that handles unexpected conditions. A much better way to write
this is:
if ( "AT".equalsIgnoreCase( key ) ) {
// do something
}
The reason is simple. "AT" is a constant and therefore never going to be an
unexpected value like null. It looks a little weird at first but it is
tremendously useful to know that this code can't break and almost certainly
a null value for key should be expected to not pass the equality test.
Another small point. The code is much better described in most cases by
using a named constant as in:
class x {
public static final String AT_TEST = "AT";
void testMethod( String key ) {
if ( AT_TEST.equalsIgnoreCase( key ) ) {
// do something
}
}
}

Thanks everyone. I actually used key.equalsIgnoreCase("AT") and its works
perfectly.
