Java中四种线程池的使用示例详解

public class ThreadPoolExecutorTest { public static void main(String[] args) { ExecutorService fixedThreadPool =Executors. newFixedThreadPool(3);  for (int i =1; i<=5;i++){  final int index=i ;  fixedThreadPool.execute(new Runnable(){   @Override   public void run() {   try {   System.out.println("第" +index + "个线程" +Thread.currentThread().getName());   Thread.sleep(1000);   } catch(InterruptedException e ) {    e .printStackTrace();   }  }   }); } }}
