停止特定的Java线程(Stopping a specific java thread)

停止特定的Java线程(Stopping a specific java thread)

我有一个“addCashier”按钮，它正在创建一个名为“Cashier”的线程，现在这个线程只是简单地在线程的run（）方法中每隔4秒产生一次，一个while（true）循环。 一切都很好，但现在我想添加一个按钮来模拟收银员注销。 我在我的while循环onDuty和一个公共函数logOff（）中添加了一个布尔变量，它将onDuty布尔值设置为false以使我脱离run的while循环。 我现在的问题是来自我的gui类如何在特定线程上调用函数？ 每个收银员线程都是在运行时生成的，所以我不知道他们的名字。

我希望我有道理。 提前致谢。

I have a button "addCashier" which is creating a thread called "Cashier" now this thread is just simply generating orders every 4 seconds, a while(true) loop in the run() method of the thread. All is good there, but now I want to add a button to simulate cashiers logging off. I added a boolean variable to my while loop onDuty and a public function logOff() which sets this onDuty bool to false to get me out of the run's while loop. My problem now is from my gui class how can I call a function on a specific thread? Each cashier thread has been generated at runtime so I don't know their names.

I hope I made sense. Thanks in advance.

最满意答案

Thread t = CashierThread(); //keep the reference to thread somewhere...

现在使用内置中断标志而不是布尔属性：

public void run() { while(!Thread.currentThread().isInterrupted()) { //... } }

当您想通过单击按钮来转动线程时，只需调用：

t.interrupt();

当然，您需要从客户端代码访问t变量。

Thread t = CashierThread(); //keep the reference to thread somewhere...

Now instead of a boolean property use built-in interrupted flag:

public void run() { while(!Thread.currentThread().isInterrupted()) { //... } }

When you want to turn of the thread by clicking on a button simply call:

t.interrupt();

Of course you need to have access to t variable from the client code.
