Java 执行器服务检查所有任务是否完成

在提交新的任务批之前，我想检查是否所有executor服务任务都已完成 这是我的密码：

     ExecutorService executorService = Executors.newFixedThreadPool(concurrency);
     for(int i=0;i<batch;i++){      
  
        for(int j=0;j<concurrency;j++) {
            executorService.submit(new DOTASK(0,loopTimes));
        }
      
        while(executorService != done){
                    // wait
             }
            System.out.println("Batch "+i+"Complete")

        }
        executorService.shutdown();
        executorService.awaitTermination(1, TimeUnit.DAYS);

ExecutorService ExecutorService=Executors.newFixedThreadPool（并发）；
for（int i=0；i是您的一个选项

ExecutorService executorService = Executors.newFixedThreadPool(concurrency);
for(int i=0;i<batch;i++){      

    CountLatchDown latch = new CountDownLatch(concurrency);
    for(int j=0;j<concurrency;j++) {
        executorService.submit(new DOTASK(0,loopTimes));
    }
    //in each DOTASK thread invoke latch.countDown()
    latch.await();
    System.out.println("Batch "+i+"Complete")

}
executorService.shutdown();
executorService.awaitTermination(1, TimeUnit.DAYS);

ExecutorService ExecutorService=Executors.newFixedThreadPool（并发）；
对于（int i=0；i您可以使用
CountDownLatch
或
join（）
您可以使用
waittermination（）
等待，就像您已经做的那样。您有什么问题？
