Java Thread.stop（）vs Thread.interrupt（） [英] Java Thread.stop() vs Thread.interrupt()

问题描述

我有以下代码：

renderThread = new Thread(new Runnable() {

    @Override
    public void run() {
        for (int i = 0; i < 10000000; i++) {
            System.out.println("Number: " + i);
        }
    }
});

renderThread.start();

try {
    Thread.sleep(100);
} catch (InterruptedException ex) {
    ex.printStackTrace();
}

renderThread.interrupt(); //It should stop, but it does not stop.

renderThread.interrupt（）不会中断线程，它继续运行。如果我用 .stop（）替换 renderThread.interrupt（），则线程停止。但是，不推荐使用 .stop（）。
然后，如果 stop 被弃用且中断没有，那么停止线程的正确方法是什么工作？

renderThread.interrupt() does not interrupt the thread, it continues to run. If I replace renderThread.interrupt() with .stop(), then the thread stops. However, .stop() is deprecated. Then, what is the proper way of stopping a thread, if stop is deprecated and interrupt does not work?

推荐答案

当你调用interrupt（）时，它会触发一个布尔标志，告诉它应该停止的运行函数。这就是为什么我经常写这样的运行函数。

When you call interrupt() it triggers a boolean flag which tells the run function it should stop. That is why I usually write my run functions like this.

void run()
{
    while(!Thread.interrupted())
    {
        //Do something
    }
}

仅仅因为你打电话给中断并不意味着线程会立即停止或完全停止。这取决于运行函数中的内容。

Just because you call interrupt doesn't mean the thread will stop immediately or at all. It depends on what is in the run function.
