BlockingQueue队列实现线程池

1）BlockingQueue队列实现线程池
应用场景1：系统需要开启多线程接收日志文件，有时开启线程数过大占用内存，因此启用线程池处理接收日志。

/**

public class ReapFileThreadPool {

    private static ThreadPoolExecutor executor = 
            new ThreadPoolExecutor(10, 15, 100, TimeUnit.MILLISECONDS, new LinkedBlockingQueue());

    public static void execute(Runnable myThread){
        executor.execute(myThread);
    }

}

2）BlockingQueue实现消息队列
应用场景2：应用BlockingQueue队列实现后台数据处理进程展示，前台定时读取队列信息。

public class BlockingQueueLog {

    final static int FILE_QUEUE_SIZE = 50;// 阻塞队列大小  
    final static BlockingQueue queue = new ArrayBlockingQueue(
            FILE_QUEUE_SIZE);

    public static boolean offString(String msg){
        return queue.offer(msg);
    }

    public static List
