是否可以在Java中为一组线程定义执行顺序 [英] is it possible to define execution order for a set of threads in java

问题描述

我的理解是，理论上线程是并行执行的. JVM决定；当有资源可用时(根据某种算法)从等待线程队列中选择哪个线程.

My understanding is that threads in theory are executed in parallel. JVM decides; when a resource is available which thread to pick from the waiting thread queue (based on some algorithm).

因此，我们不能为线程提供/强制执行序列.

Hence we can not provide/enforce a sequence of execution for threads.

说我的Java应用程序有3个线程，t1，t2和t3.

Say my java application has 3 threads, t1, t2 and t3.

出于某些特定原因；我希望线程按此顺序执行: t3然后t1然后t2.

For some specific reason; I want the threads to execute in this order: t3 then t1 and then t2.

是否可以这样做? java是否提供了这样做的任何方式?

Is it possible to do this? Does java provided any way of doing this?

推荐答案

使用执行程序:

executor.execute(runnable1);
wait();
executor.execute(runnable2);
wait();
executor.execute(runnable3);
wait();

当然，每个Runnable必须以notify()语句结尾.

And of course, each Runnable has to end with a notify() statement.
