本文展示了一个使用Java实现的简单并发程序示例，通过ArrayBlockingQueue进行任务分发，多个消费者线程从队列中获取任务并处理，演示了线程间的同步与通信。

	public static void main(String args[]){
		
		final BlockingQueue<String> queue = new ArrayBlockingQueue<String>(1);
		
		for (int i=0; i<4; i++){
			new Thread(new Runnable() {
				@Override
				public void run() {
					while (true){
						try {

							String log = queue.take();
							printLog(log);

						} catch (InterruptedException e) {
							// TODO Auto-generated catch block
							e.printStackTrace();
						}
					}
				}
			}).start();
		}
		
		
		
		for (int i=0; i<16; i++){
			final String log = "" + (i+1);
			{
				try {
					queue.put(log);
				} catch (InterruptedException e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}
		}
	}
	
	private static void printLog(String log){
		System.out.println(log + ":" + System.currentTimeMillis() / 1000);
		
		try {
			Thread.sleep(1000);
		} catch (InterruptedException e) {
			e.printStackTrace();
		}
	}
}

输出结果是：
