线程池中submit方法和execute的区别

两者区别在于一个有返回值，一个没有返回值

贴代码

//submit()
Future<?> submit = executorService.submit(new Runnable() {
    @Override
    public void run() {                        
        System.out.println(Thread.currentThread().getName());
    }
});

执行结果，正常执行返回值为null

 

 

//execute()
executorService.execute(new Runnable() {
    @Override
    public void run() {                        
        System.out.println(Thread.currentThread().getName());
    }
});

不存在返回值
