可运行的调用notifyall来唤醒自己-Java

Question

I have a class that implements Callable , X , and a class that implements Runnable , Y .

Y has a collection of X 's , and when one of X 's ends I want to wake Y , X has Y as a private field, can I just use Y.notifyAll() to wake it?

Answer 1

If you have Y as a private member of X , you can call a method in Y directly.

Y.notifyAll() will notify all threads that already called wait() on the same instance of Y .
