youdao

Timer has a number of schedule() overloads, indicating whether a given task is to be one-shot or a repeating, and takes a TimerTask instance to fire.

Timer 有许多 schedule() 重载，它们提示某一任务是一次性还是重复的，并且有一个启动的 TimerTask 实例。

youdao

After I've defined a Timer instance, I then need to schedule it to launch while also forcing JUnit to hang around for the Timer instance to complete.

定义了Timer实例后，我就需要确定其何时运行，同时强制JUnit挂起直至Timer实例完成。
