大家好，我尝试从txt文件中获取命令，并且我想在一定时间段内运行这些命令。我可以从txt文件中正确获取命令，但是当我想使用处理程序来执行这些命令时一定的时间，但是有一个问题。问题在于处理程序可以一起工作，另一个处理程序在第一个处理程序的时间到期之前就开始起作用了。当我使用相同的可运行程序执行此操作时，它执行的操作也相同。
我的txt文件如下所示： Ileri，5,1 / n Sol，10,1 / n-> 10是操作时间1是重复次数。 凹陷，5,1 / n Geri，10,1 / n
我的输出：
I / System.out：Ileri 6000 1个 I / System.out：Sol 11000 1个 I / System.out：下垂 6000 1个 I / System.out：Geri 11000 1个 I / System.out：A

我通过使用thread.sleep（）解决了我的问题；我在这里写是因为有人可能需要我的代码。
