Is it possible to assign a variable in a while loop?

Question

I'm looking for a way to use scanner in a while loop, without advancing twice.

String desc = "";
while (!scanner.next().equals("END")) {
    desc = desc + scanner.next();
}           

As you can see, when scanner.next() is called in the while loop's condition and inside of the while loop itself. I want it to advance the scanner only once. Is there any way to do that?

Yes it is possible. You should also check that the Scanner has more tokens in its input

String desc = "";
String next = null;
while (scanner.hasNext() && !(next = scanner.next()).equals("END")) {
    desc = desc + next;
}
