Java并发学习(一)-Executor

Executor是java并发包里面的一个接口，其里面只有一个方法：
void execute(Runnable command);
通常我们使用Executor时会使用ExecutorService接口，该接口集成了Executor接口同时还实定义了其它方法，具体可以从代码中看出：

public interface ExecutorService extends Executor {


void shutdown();

    List<Runnable> shutdownNow();


boolean isShutdown();

boolean isTerminated();
boolean awaitTermination(long timeout, TimeUnit unit)throws InterruptedException;
    <T> Future<T> submit(Callable<T> task);
    <T> Future<T> submit(Runnable task, T result);
    Future<?> submit(Runnable task);
    <T> T invokeAny(Collection<? extends Callable<T>> tasks,long timeout, TimeUnit unit)
throws InterruptedException, ExecutionException, TimeoutException;
}
