We can say that in this case,Thread-3has to wait untilThread-2completes and alsoThread-2has to wait untilThread-1completes its execution. Thread-2has to callThread-1.join(), andThread-3has to callThread-2.join()so that they will wait until the completion of the other thread. 2. Ja...
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...

thread.join(); } catch (InterruptedException e) { e.printStackTrace(); }*/ System.out.println(a); } } 运行代码,貌似永远都看不到a的值是5,而每次都是0,原因很简单的,因为在thread中的run方法中进行a的增值操作,这些可能都是需要时间的,但是此时main线程中的System.out.println方法已经执行了,所以很...

Java并发之Thread.join 蔫茄子的架构师之路 百家号02-1914:32 前言:刚刚开始学习多线程的Thread的时候就知道了join这个方法,一直对它只是懵懂的认知。Waits for this thread to die是这个方法的作用。 1. 看一个例子 public class SynchronizedClassClass implements Runnable{ static SynchronizedClassClass synchronized...
