Negation of boolean

Hi again :)

One of those "Can yuo do this?" -type questions again:
Anything wrong with:

boolean sequenceContinues = false;
if([condition]){
sequenceContinues = !sequenceContinues;
}
else{}

?

Rewrite that as

boolean sequenceContinues = ([condition]);

No, that doesn't do the same thing.

That wouldn't accomplish what I'm trying to do. sequenceContinues is
supposed to change from flase to true or vice versa...
I actually mis-quoted my code, the if-block should be inside a while-loop.
Sorry about the confusion.

Would it not be simpler to write:

boolean sequenceContinues = conditionexpression;

Nothing objectionable that I can see.  You could optimiize
(or obfuscate) the inversion a little:

sequenceContinues ^= true;

You just want a loop that change the value of a boolean ??? Here is a simple
class with a main method which print the doSequence value and switch it 10
times.

public class SwitchVal {

public static void main(String[] args) {

boolean doSequence = false;

for (int i=0; i<10; i++){

System.out.println(doSequence);

doSequence = !doSequence;

}

}

}

Actually, I want it to change the value only if the "if" condition is
met (and do some other stuff as well, regardless of whether it changed
the value or not.) (That other stuff varies depending on the value of
the boolean.)

It appears that I've misunderstood the question... Can it be more clear?
Maybe may I help;

How many of you know what this code does without looking it up?

sequenceContinues ^= condition;
