如何确保Java线程按特定顺序运行:How to ensure Java threads run in a particular order

给出三个打印字母A-C的线程1-3，如何保证输出顺序?

Given three threads, 1-3, that print a letter, A-C, how can I guarantee the output order?

我希望线程的输出为"ABCABCABC"

I would like the output of the threads to be "ABCABCABC"

问题解答

线程是独立运行的，因此，除非您做出特殊的努力来同步线程，否则您将永远不会得到这样的输出.预计3个独立运行的线程将打印随机"输出，因为要由OS来调度线程.

Threads run independently, so you will never get such output unless you perform special efforts to synchronize your threads. 3 threads that are running independently are expected to print "random" output because it is up to OS to schedule the threads.
