java多線程ExecutorService線程數(shù)量？

新增了一個(gè)Executors工廠類產(chǎn)生線程池，如下面幾個(gè)方法

- public static ExecutorService newFixedThreadPool(int nThreads)

- public static ExecutorService newSingleThreadExecutor()這些方法的返回值是ExecutorService對(duì)象，該對(duì)象表示一個(gè)線程池，可以執(zhí)行Runnable對(duì)象或者Callable對(duì)象代表的線程。它提供了如下方法：

- Future<?> submit(Runnable task)

- <T> Future<T> submit(Callable<T> task)
