Waiting for the finalization of a thread In some situations, we will have to wait for the finalization of a thread. For example, we mayhave a program that will begin initializing the resources it needs before proceeding with therest of the execution. We can run the initialization tasks as ...

1.2 join() 的作用 让父线程等待子线程结束之后才能继续运行。 我们来看看在 Java 7 Concurrency Cookbook 中相关的描述(很清楚地说明了 join() 的作用): Waiting for the finalization of a thread In some situations, we will have to wait for the finalization of a thread. For example, we mayhave a...
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 until the object called finishes its ...
Thread thread =newThread(ft); thread.start; System.out.println(ft.get); } 继承Thread 类 同样也是需要实现 run 方法,因为 Thread 类也实现了 Runable 接口。 当调用 start 方法启动一个线程时,虚拟机会将该线程放入就绪队列中等待被调度,当一个线程被调度时会执行该线程的 run 方法。
Thread.sleep(10); System.out.println("interrupt start"); t1.interrupt();*/} } join join方法允许一个线程等待另一个线程运行完成,通过调用t.join方法来实现,这会使当前线程暂停执行,等待t的完成 packagemthread;publicclassThreadJoin {staticclassCounterimplementsRunnable{ ...

To quote from the Thread.join()method javadocs:join()Waitsforthisthread to die.There is a thread that is running your example code which is probably the main thread.The main thread creates and starts the t1 and t2 threads.The two threads start runninginparallel.The main thread calls t1....
