无法在Runnable中实现run（）

Question

public class Reader extends Thread{

...

    public static void run()throws InterruptedException{

        Monitor mon = new Monitor();

            for(int i = 0; i <10; i++)
            {
                mon.MonEntry();



                Read("file.txt");

                mon.MonExit();
            }

    }
}

I cannot use extends Thread for some reason because it says: cannot implement run() in Runnable. I don't see what I did wrong? When we call extends Thread instead of implement Runnable shouldn't we be able to use our own implementation of run() for starting threads?

Answer 1

It is just a public void. No static.

Please, have a look at the documentation . It clearly shows that it is public void :-)

Also, avoid the name Reader because there is a class in java.io package which is named Reader and using names that are already present in Java packages is discouraged :)

Answer 2

Thread类里面的run方法不是静态的
