包路径：org.apache.commons.lang.time.StopWatch
类名称：StopWatch

StopWatch介绍

[英]StopWatch provides a convenient API for timings.

To start the watch, call #start(). At this point you can:

#split() the watch to get the time whilst the watch continues in the background. #unsplit() will remove the effect of the split. At this point, these three options are available again.
#suspend() the watch to pause it. #resume() allows the watch to continue. Any time between the suspend and resume will not be counted in the total. At this point, these three options are available again.
#stop() the watch to complete the timing session.

It is intended that the output methods #toString() and #getTime() should only be called after stop, split or suspend, however a suitable result will be returned at other points.

NOTE: As from v2.1, the methods protect against inappropriate calls. Thus you cannot now call stop before start, resume before suspend or unsplit before split.

split(), suspend(), or stop() cannot be invoked twice
unsplit() may only be called if the watch has been split()
resume() may only be called if the watch has been suspend()
start() cannot be called twice without calling reset()

This class is not thread-safe
[中]StopWatch为计时提供了方便的API。
要启动手表，请调用#start（）。此时，您可以：
*#分割（）手表以获取时间，同时手表继续在后台运行#unsplit（）将删除拆分的效果。此时，这三个选项再次可用。
*挂起手表暂停#resume（）允许手表继续运行。暂停和恢复之间的任何时间都不计入总数。此时，这三个选项再次可用。
*#停止（）手表以完成计时任务。
输出方法#toString（）和#getTime（）只应在stop、split或suspend之后调用，但是会在其他点返回合适的结果。
注：从v2开始。1.这些方法可以防止不适当的调用。因此，您现在不能在开始之前调用stop，在暂停之前调用resume，或者在拆分之前调用unsplit。
1.split（）、suspend（）或stop（）不能被调用两次
2.unsplit（）只能在手表已拆分时调用（）
3.仅当手表已暂停（）时，才能调用resume（）
4.在不调用reset（）的情况下，无法调用start（）两次
这个类不是线程安全的
