Question

Runnable runPickWinner = new Runnable() {
        @Override
        public void run() {
            mPot.pickWinner();
        }
    };
ScheduledExecutorService execPickWinner = Executors.newScheduledThreadPool(1);
execPickWinner.scheduleAtFixedRate(runPickWinner, runPickWinnerTime.longValue(), runPickWinnerTime.longValue(), TimeUnit.MINUTES);

我收到以下错误：

java.lang.IllegalArgumentException

scheduleAtFixedRate(Runnable command, long initialDelay, long period, TimeUnit unit)似乎是一个错误，但它没有意义它们是Integer类型，但后来我调用longValue()这应该把它们变成一个long。我只是通过对其中的值进行硬编码来实现这一点，例如，如果我使用10L或者仅使用10，那么这不会。

scheduleAtFixedRate方法的IllegalArgumentException
