Why Can't You Set The Value Of A Boolean Wrapper?

Question

I don't see any methods in the Boolean class that would allow you to set the value of the underlying primitive. It seems that once it's created, that's it.
My reason for wanting to do this is that I have some synchronized code which is synchronizing on the value of boolean flag. Since you cannot synchronize on a primitive type, I decided to wrap it in a Boolean object....
Do I have to create my own custom class for this? Not that it would be hard, but it just seems like I shouldn't have to.
Thanks,
John
PS: If the above wasn't clear, the synchronized code looks like this:
//client code
synchronized (myBooleanFlag) {
  while (!myBooleanFlag.booleanValue())
    myBooleanFlag.wait();
//code which changes the flag
synchronized (myBooleanFlag) {
  myBooleanFlag.setValue(true); //WAIT!! There's no method to do this
  myBooleanFlag.notifyAll();

Hi,
You usually write it like this:
Object variableLock = new Object();
boolean variable = false;
synchronized (variableLock) {
variable = true;
}So, you don't have to synchronize on the value that
you want to change, just make all competing code
synchronize on the same (guard) object.Yes. That's what I want. Once again, Kaj saves the day!
Thanks,
