下面是一个使用join方法的示例代码: publicclassJoinExample{publicstaticvoidmain(String[]args)throwsInterruptedException{Threadthread=newThread(newMyRunnable());thread.start();thread.join();// 等待线程执行完毕System.out.println("All threads have finished.");}}classMyRunnableimplementsRunnable{@Overridepubli...
In this tutorial, we will learnhow to join two Threads and why there is a need to join Threads in java.We will explore in detail theThread.join()API and the different versions of the same along with practical examples. We will also see how we can end up in a deadlock situation while...
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 threads and wait for its finalizationbefore ...
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...
join() method ofJava.lang.Threadclass is used to maintain the order of excution of threads. Using join() method can make currently executing thread wait for some other threads finish their tasks. Implemention of join() method join() method is overloaded in thread class, there are three forms...
void notifyAll() Wakes up all threads that are waiting on this object's monitor.有了对wait方法原理的理解,notify方法和notifyAll方法就很容易理解了。既然wait方式是通过对象的monitor对象来实现的,所以只要在同一对象上去调用notify/notifyAll方法,就可以唤醒对应对象monitor上等待的线程了。notify和notifyAll的区...
System.out.println("Thread 2 finished");});thread1.start();thread2.start();try{thread1.join();// 主线程等待thread1完成thread2.join();// 主线程等待thread2完成}catch(InterruptedExceptione){e.printStackTrace();}// 所有线程都执行完毕后继续执行主线程System.out.println("All threads have ...

8.Java中的并发工具类 9.Java中的线程池 10.Executor框架 一、使用方式。 join()是Thread类的一个方法,启动线程后直接调用,例如: Threadt=newAThread();t.start();t.join(); 二、为什么要用join()方法 在很多情况下,主线程生成并起动了子线程,如果子线程里要进行大量的耗时的运算,主线程往往将于子线程之...
