To facilitate the discussion, I will post the code below：
Method of Thead A!
public void await() throws InterruptedException {
synchronized (lock) {
while (!triggered) {
Thread thread = Thread.currentThread();
try {
waitersSet.add(thread);
lock.wait();
} finally {
waitersSet.remove(thread);
}
}
}
}
Method of Thead B!
public void trigger() {
synchronized (lock) {
triggered = true;
lock.notifyAll();
}
}
