推荐答案
对于某些代码的固定延迟执行，使用 timer对象可能是更好的方法，例如 java.util.Timer 或 javax.swing.Timer ，甚至 AnimationTimer ，具体取决于您正在尝试完成.话虽如此，无法保证频率和1000/s(或1ms的周期)的频率非常快，并且java.util.Timer和javax.swing.Timer不能跟上.
For the fixed-delay execution of some code, it might be a better approach to use a timer object, such as java.util.Timer or javax.swing.Timer, or even AnimationTimer, depending on what you're trying to accomplish. This being said, it's not possible to guarantee a frequency and a frequency of 1000/s (or period of 1ms) is quite fast, and java.util.Timer and javax.swing.Timer won't be able to keep up.
