计算线程的总循环次数

Question

从主线程开始，我启动了20个线程。我每个线程（例如）执行5次迭代。如何计算周期值。换句话说，我希望被连续编号。计算发生在线程内部。 （它知道它的编号。）我稍后希望能够说出诸如“ 127号循环中发生错误”之类的内容。

可以这么说，我正在寻找计算公式。

非常感谢您！

Example:
Thread: 0 Iteration 0 = Cycle 1
Thread: 0 Iteration 1 = Cycle 2
Thread: 0 Iteration 2 = Cycle 3
Thread: 0 Iteration 3 = Cycle 4
Thread: 0 Iteration 4 = Cycle 5
Thread: 1 Iteration 0 = Cycle 6
Thread: 1 Iteration 1 = Cycle 7
Thread: 1 Iteration 2 = Cycle 8
Thread: 1 Iteration 3 = Cycle 9
Thread: 1 Iteration 4 = Cycle 10
Thread: 2 Iteration 0 = Cycle 11
...
Thread: 9 Iteration 0 = Cycle 46
Thread: 9 Iteration 1 = Cycle 47
Thread: 9 Iteration 2 = Cycle 48
Thread: 9 Iteration 3 = Cycle 49
Thread: 9 Iteration 4 = Cycle 50

Answer 1

使用AtomicInteger。这是int的线程安全实现，因此每个线程都可以访问它并计算迭代次数。
