getHoldCount():查询当前线程保持锁定的个数,也就是调用lock()方法的次数。 getQueueLength():返回正等待获取此锁定线程数,如果一共开启了5个线程,一个线程执行了await()方法,那么在调用此方法是,返回4,说明此时正有4个线程在等待锁的释放。 getWaitQueueLength:返回同一个Condition类的等待线程数。如果有同时开...
lock.getHoldCount(): 获取保持锁定的线程数(lock中的数量); lock.getQueueLength(): 获取等待获取锁定的线程数; lock.getWaitQueueLength(cond): 获取cond.await中的线程数量;
