背景：我有三個線程。ThreadA 負責向隊列中寫入元素，如果隊列已滿，則通知 ThreadC 從隊列中讀取元素。ThreadB 是另一個條件，如果隊列未滿，但時間超過 5 秒，則 Thread 通知 threadC 從隊列中取出元素，最后，ThreadC 通知 ThreadB 刷新其時間戳。import java.util.concurrent.ArrayBlockingQueue;import java.util.concurrent.TimeUnit;import java.util.concurrent.locks.Condition;import java.util.concurrent.locks.Lock;import java.util.concurrent.locks.ReentrantLock;public class Main {    private Lock lock = new ReentrantLock();    private Condition conA = lock.newCondition();    private Condition conB = lock.newCondition();    private Condition conC = lock.newCondition();    ArrayBlockingQueue<Integer> readQueueA = new ArrayBlockingQueue<>(3);    public static void main(String[] args) {        Main main1 = new Main();        try {            ThreadA threadWrite = main1.new ThreadA();            Thread threadOut = new Thread(threadWrite);            threadOut.start();            ThreadB threadB = main1.new ThreadB();            Thread threadBB = new Thread(threadB);            threadBB.start();            ThreadC threadRead = main1.new ThreadC();            Thread threadIn = new Thread(threadRead);            threadIn.start();        } catch (Exception ex) {            ex.printStackTrace();        }    }但是，輸出不是我所期望的，為什么一開始ThreadB outPut TimeOut Zzz？我認為應該不輸出這個項目。因為ThreadA喚醒了ThreadC，下一步應該exec ThreadC并且Thread可以在短時間內(nèi)運行完成而不超過5s.誰能幫我解釋或修復它？感謝你！
