博客给出了Executors相关代码示例，Executors在信息技术领域常用于线程池的创建等操作，代码示例能帮助开发者更好理解和运用Executors。

代码示例：

private static void ExecutorMethod() {
	//ExecutorService service = Executors.newSingleThreadExecutor(); //一池一线程
	ExecutorService service = Executors.newFixedThreadPool(3);			//一池三线程
	//ExecutorService service = Executors.newCachedThreadPool();     //一池N线程
	Future<Integer> result = null;
	try {
		for (int i = 1; i <= 15; i++) {
			result = service.submit( () -> {
				Thread.sleep(400);
				System.out.print(Thread.currentThread().getName());
				return new Random().nextInt(10);
			} );
			System.out.println("  ********result: "+result.get());
		}
	} catch (Exception e) {
		e.printStackTrace();
	} finally {
		service.shutdown();
	}
}

private static void ScheduledExecutorMethod() {
	ScheduledExecutorService service = Executors.newScheduledThreadPool(5); //带延时的线程池
	Future<Integer> result = null;
	try {
		for (int i = 1; i <= 15; i++) {
			result = service.schedule(() -> {
				System.out.print(Thread.currentThread().getName());
				return new Random().nextInt(10);
			}, 2, TimeUnit.SECONDS);
			System.out.println("  ********result: "+result.get());
		}
	} catch (Exception e) {
		e.printStackTrace();
	} finally {
		service.shutdown();
	}
}
