My guess is that p isn't null. It's probably "". Try println("|"+p+"|") to
be sure - if you see ||, it's "".
Anyway, I normally create a static utility method that checks to see that
strings are valid. It checks for the string passed in not being null, and
not of zero length and returns true if both are true, otherwise false. Sort
of like the perl method defined.
Then, I would do
if(Utils.valid(p))
{
// do something
}
else
{
// p was either null or zero length
}
hope that helps.
