Java ScheduledExecutorService定时任务案例讲解

class MyScheduledExecutor implements Runnable {
    
    private String jobName;
    
    MyScheduledExecutor() {
        
    }
    
    MyScheduledExecutor(String jobName) {
        this.jobName = jobName;
    }

    @Override
    public void run() {
        
        System.out.println(jobName + " is running");
    }
}

public static void main(String[] args) {
        ScheduledExecutorService service = Executors.newScheduledThreadPool(10);
        
        long initialDelay = 1;
        long period = 1;
        // 从现在开始1秒钟之后，每隔1秒钟执行一次job1
        service.scheduleAtFixedRate(new MyScheduledExecutor("job1"), initialDelay, period, TimeUnit.SECONDS);
        
        // 从现在开始2秒钟之后，每隔2秒钟执行一次job2
        service.scheduleWithFixedDelay(new MyScheduledExecutor("job2"), initialDelay, period, TimeUnit.SECONDS);
    }
