个人认为”Java7 Concurrency Cookbook”的定义较为清晰: join() method suspends the execution of the calling thread until the object called finishes its execution. 也就是说,t.join()方法阻塞调用此方法的线程(calling thread),直到线程t完成,此线程再继续;通常用于在main()主线程内,等待其它线程完成再结束m...
We can run the initialization tasks as threads and wait for its finalization before continuing with the rest of the program. For this purpose, we can use the join() method of the Thread class. When we call this method using a thread object, it suspends the execution of the calling thread...
我们在Thread类里面可以找到一个exit()方法,上面备注写着:This method is called by the system to give a Thread a chance to clean up before it actually exits. 这么简单的英文大家应该都能看懂吧? 里面有这么一段代码: if (group != null) { group.threadTerminated(this); group = null; } void ...
In other words,thismethod behaves exactlyasifit simply performs the call wait(0). The current thread must ownthisobject's monitor. The thread releases ownership of this monitor and waits until another thread notifies threads waiting on this object's monitor to wake up either through a call to ...
The current thread must own this object's monitor. The thread releases ownership of this monitor and waits until another thread notifies threads waiting on this object's monitor to wake up either through a call to the notify method or the notifyAll method. The thread then waits until it can...
A static commonPool() is available and appropriate for most applications. The common pool is used by any ForkJoinTask that is not explicitly submitted to a specified pool. Using the common pool normally reduces resource usage (its threads are slowly reclaimed during periods of non-use, and rei...
In the example given below Python string join() method is used to join the set with the character #. Since the set allows only unique values, only one value is printed out of the repeated values (in this case '9'):Open Compiler sets = {'9','7', '2','9','3','9'} character...
* traversal in method helpJoinTask. This is only a hint because a * worker might have had multiple steals and this only holds one * of them (usually the most current). Declared non-volatile, * relying on other prevailing sync to keep reasonably current. */ int stealHint; ForkJoinWorker...
(2) join(long), join(long, long) 是synchronized method,同步的对象是当前线程实例。 (2) 无参版本和两个参数版本最终都调用了一个参数的版本。 (3) join() 和 join(0) 是等价的,表示一直等下去;join(非0)表示等待一段时间。 从源码可以看到 join(0) 调用了Object.wait(0),其中Object.wait(0) 会...
