java中实现Runnable接口方式是什么？

public class MyRunnable implements Runnable {

@Override

public void run() {

    for (int i = 0; i < 1000; i++) {

        System.out.println("run类线程" + i);

    }

}

public static void main(String[] args) {

    MyRunnable myRunnable = new MyRunnable();

    //使该线程开始执行；Java虚拟机将调用run此线程的方法。

    new Thread(myRunnable).start();

    //myThread.run();

    for (int i = 0; i < 1000; i++) {

        System.out.println("主线程"+i);

    }

}

}
