java.util.Timer.schedule如何避免启动时指定时间过了就立刻执行一次？

Question

schedule的开始时间设置的是一个固定时间，比如中午12点，如果过了12点启动，那么会立刻执行一次，有没有办法能过了任务的指定开始时间就不执行了等下一次？

Answer 1

public void schedule(TimerTask task, long delay, long period)

Isn’t it possible to use this interface? Calculate the number of milliseconds from the current time to 12 noon delay，period是今天中午12点至明天中午12点就是24小时的毫秒数。这样如果当前时间超过12点了。那delay and it will be the next 12 o'clock.

Answer 2

Can you add a method to judge whether the current time is not equal to the scheduled time and not start it? I have never done this...
