关于Future.cancel(mayInterruptIfRunning)方法的参数的问题

mayInterruptIfRunning设成false话，不允许在线程运行时中断，设成true的话就允许。 
可以参考下面的代码来理解，如果设为false的话，会打印到99999，如果设成true的话，可能就打印不到99999

package interrupt;
import java.util.concurrent.ExecutorService;
import java.util.concurrent.Executors;
import java.util.concurrent.Future;

public class Future01 {

    public static void main(String[] args) {
        ExecutorService eService = Executors.newFixedThreadPool(5);
        Future<?> future= eService.submit(new RunFuture());
        try {
            Thread.sleep(10);
            future.cancel(false);
            //future.cancel(true);
            System.out.println("haha---------------");
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

}
class RunFuture implements Runnable{
    int i=0;
    @Override
    public void run() {
        while (i<100000&&!Thread.currentThread().isInterrupted()/**/) {
            System.out.println("i++:"+i);
            i++;
        }

    }

}
