我每 1 分钟要执行三个独立的任务。在这里，我开发了两个选项。

选项1

ScheduledExecutorService service1 = Executors.newScheduledThreadPool(1); 
ScheduledExecutorService service2 = Executors.newScheduledThreadPool(1); 
ScheduledExecutorService service2 = Executors.newScheduledThreadPool(1); 
service1.scheduleAtFixedRate(new task1(), 0, 60, TimeUnit.SECONDS); 
service2.scheduleAtFixedRate(new task2(), 0, 60, TimeUnit.SECONDS); 
service3.scheduleAtFixedRate(new task3(), 0, 60, TimeUnit.SECONDS);

选项2

ScheduledExecutorService service = Executors.newScheduledThreadPool(3);
service.scheduleAtFixedRate(new task1(), 0, 60, TimeUnit.SECONDS);
service.scheduleAtFixedRate(new task2(), 0, 60, TimeUnit.SECONDS);
service.scheduleAtFixedRate(new task3(), 0, 60, TimeUnit.SECONDS);

我的问题是哪个选项是首选？Option1 是否消耗更多的系统资源？
