java中实现runnable的类是否可以使用run()以外的方法？

public class MyRunnable implements Runnable {
    public void run() {
        // 在这里实现多线程代码
    }
}

public class Main {
    public static void main(String[] args) {
        MyRunnable myRunnable = new MyRunnable();
        Thread thread = new Thread(myRunnable);
        thread.start();
    }
}

public class MyRunnable implements Runnable {
    public void run() {
        // 在这里实现多线程代码
    }
}

public class Main {
    public static void main(String[] args) {
        MyRunnable myRunnable = new MyRunnable();
        ExecutorService executorService = Executors.newFixedThreadPool(10);
        executorService.submit(myRunnable);
    }
}

public class MyRunnable implements Runnable {
    public void run() {
        // 在这里实现多线程代码
    }
}

public class Main {
    public static void main(String[] args) {
        MyRunnable myRunnable = new MyRunnable();
        CompletableFuture.runAsync(myRunnable);
    }
}
