线程池实践：10个线程处理1000个下载请求

使用阻塞队列存储下载链接，使用固定数量线程池，通过实现Runnable接口提交下载任务

public class Main {
	private static final int capacity=1000;
	private static BlockingQueue<String> storage=new LinkedBlockingQueue<>(capacity);
	static class Downloader implements Runnable {
		@Override
		public void run() {
			try {
				//模拟下载事件处理：
				System.out.println(Thread.currentThread().getName() + " downloads: " + storage.take());
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
		}
	}
	public static void main(String[] args){
		//模拟下载链接准备：
		for(int i=0;i<capacity;i++){
			try {
				storage.put("https://mydrive.com/user/gigabit/storage/file"+(i+1)+".zip");
			} catch (InterruptedException e) {
				e.printStackTrace();
			}
		}
		//创建线程池：
		ThreadPoolExecutor downloaderPool=new ThreadPoolExecutor(
				10,//CorePoolSize
				10,//MaxPoolSize
				1,//KeepAliveTime
				TimeUnit.SECONDS,
				new LinkedBlockingQueue<Runnable>());
		//向线程池提交1000次下载任务：
		for(int i=0;i<capacity;i++){
			downloaderPool.execute(new Downloader());
		}
	}
}

执行结果：
