Executor：
Executor的实现可以根据实际需求延展不同的逻辑：
1. 对于提交的任务同步或者异步执行，如下同步执行：
class ThreadPerTaskExecutor implements Executor { public void execute(Runnable r) { new Thread(r).start(); }
2. 另起线程执行任务，如下：
class ThreadPerTaskExecutor implements Executor { public void execute(Runnable r) { new Thread(r).start(); }
3. 对于执行的任务添加限制：
class SerialExecutor implements Executor { final Queue<Runnable> tasks = new ArrayDeque<Runnable>(); final Executor executor; Runnable active; SerialExecutor(Executor executor) { this.executor = executor; } public synchronized void execute(final Runnable r) { tasks.offer(new Runnable() { public void run() { try { r.run(); } finally { scheduleNext(); } } }); if (active == null) { scheduleNext(); } } protected synchronized void scheduleNext() { if ((active = tasks.poll()) != null) { executor.execute(active); } } }}
