notifyall词根词缀

In essence, wait() and notify()/ notifyAll() act as a simple signaling mechanism, allowing the Drop to coordinate between the Producer and the Consumer threads, one take to each put.

从本质上说，wait（）和notify（）/notifyAll（）允许一种简单的信令机制，它允许Drop在Producer和Consumer线程之间进行协调，每个put都有相应的take。

Careful: replacing the notifyAll() with notify() solves the problem in this scenario but will fail on others!)

注意：用notify（）取代notifyAll（）能解决此情形中的问题，但是在其他情形中将会失败！

The wait() method tells the current thread to go into an inactive state and wait for another thread to call notifyAll() on that object.

wait（）方法将通知当前线程进入非活动状态，并等待另一个线对该对象调用notifyAll（）。
