Dear Greg,

What I think your problem is, is that you shouldn't be using the operators
:==, != ...
try using:

    while(!temp.equals("\n")){
        .............
        .........
        ............
    }

I forget the exact reason that the !=/== thing doesn't work for strings, I
just remeber it doesn't.

Greg,

I think your problem is you need to use the equals() method fo the
string class - you cannot compare strings with == or !=. Try something 
like

while (!(temp = in.readLine()).equals("")) // while line is not ""

Note that you may have another problem here - what happens when you
come to the end of the input file? Perhapse you could try something
like

while ((temp = in.readLine()) != null) {
        if (temp.equals(""))
                // do whatever you do if you get a blank line
        else
                // do whatever you do when you don't get a blank line
}

Hope this helps
