我上过这门课

public class EXEC implements Runnable{
 private final AtomicBoolean running = new AtomicBoolean(false);
 WebDriver driver;
public EXEC(WebDriver driver) {
    this.driver = driver;
}     
public void stop() {
    running.set(false);
}
@Override
public void run() {
    // TODO Auto-generated method stub
    String pass=SampleController.getMyVariable();
     running.set(true);
     while(running.get()){
    int i=1;
    i++;
    System.out.println(i);
 }
     Platform.exit();
}
}

在ui控制器类中，我用如下方法分配了run和quit按钮

EXEC mythread=  new EXEC(drivers);
public void run()
{mythread.run();}
public void quit()
{ mythread.stop();}
``` `mythread.run()` 为我工作。但是它没有被终止 `mythread.stop();` . 请帮我怎么弄到它
