newScheduledThreadPool

可以通过调用Executors类的静态newScheduledThreadPool（）方法来获取调度的线程池。

语法 (Syntax)

ExecutorService executor = Executors.newScheduledThreadPool(1);

例子 (Example)

以下TestThread程序显示了在基于线程的环境中使用newScheduledThreadPool方法。

import java.util.concurrent.Executors;
import java.util.concurrent.ScheduledExecutorService;
import java.util.concurrent.ScheduledFuture;
import java.util.concurrent.TimeUnit;
public class TestThread {
   public static void main(final String[] arguments) throws InterruptedException {
      final ScheduledExecutorService scheduler = Executors.newScheduledThreadPool(1);
      final ScheduledFuture<?> beepHandler = 
         scheduler.scheduleAtFixedRate(new BeepTask(), 2, 2, TimeUnit.SECONDS);
      scheduler.schedule(new Runnable() {
         @Override
         public void run() {
            beepHandler.cancel(true);
            scheduler.shutdown();			
         }
      }, 10, TimeUnit.SECONDS);
   }  
   static class BeepTask implements Runnable {
      public void run() {
         System.out.println("beep");      
      }
   }
}

这将产生以下结果。

输出 (Output)

beep
beep
beep
beep
