顺序队列实现任务以此执行-任务调度系列2

顺序队列实现任务以此执行的想法：

public class TaskManage {

    //任务队列
    private BlockingQueue<Runnable> queue = new ArrayBlockingQueue<Runnable>(10); 

    private boolean running = false;  

    public void start() {
        running = true;
        Thread t = new Thread(new OrderedJob());
        t.start();
    }  

    public void stop() {
        running = false;
    }  

    public void submit(Runnable task){
        try {
            if(queue.offer(task, 5000L, TimeUnit.MILLISECONDS) == false){
                System.out.println();
            }
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
    class OrderedJob implements Runnable {  

        @Override
        public void run() {
            while (running) {
                try {
                    Runnable job = queue.poll(5000L, TimeUnit.MILLISECONDS);
                    try {
                        if (job != null)
                            job.run();
                    } catch (RuntimeException e) {
                        // TODO: handle exception
                    }
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
        }
    }
}
