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 execution.

源码看到这,我又有了一个新的疑问:join方法内部是一个while循环。wait释放了锁,那必然会有一个人来唤醒它,程序才能够继续往下走。那必然有一个地方调用了thread对象的notify方法。 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 ...
Thread.sleep(1000); } System.out.println(threadName + " end."); } catch (Exception e) { System.out.println("Exception from " + threadName + ".run"); } } } class CustomThread extends Thread { CustomThread1 t1; public CustomThread(CustomThread1 t1){ super("[CustomThread] Thread");...
In the following example, the Thread1 thread calls the Join() method of Thread2, which causes Thread1 to block until Thread2 has completed. C# Αντιγραφή using System; using System.Threading; public class Example { static Thread thread1, thread2; public static void Main() {...
public final void join()throws InterruptedException: Waits for this thread to die. join()方法的作用,是等待这个线程结束;但显然,这样的定义并不清晰。个人认为”Java 7 Concurrency Cookbook”的定义较为清晰: join() method suspends the execution of the calling thread until the object called finishes its...
我们把上面的main方法简单改一下,用另一个线程是占住thread这个对象锁,就比较直观了: 复制 publicstaticvoid main(String[] args) throws InterruptedException {Thread thread = new Thread(new ThreadA());thread.start();new Thread(() -> {// 把thread对象作为锁占住,这样下面的join里面的wait只有等锁释放...
join(long milliseconds)方法的示例文件名：TestJoinMethod2.javaclass TestJoinMethod2 extends Thread{public void run(){for(int i=1;i<=5;i++){try{Thread.sleep(500);}catch(Exception e){System.out.println(e);}System.out.println(i);}}public static void main(String args[]){TestJoinMethod2 ...
