/**
* The application of thread interruption in the swing progress bar is used, and the setValue () method of JProgressBar is called in run.
* <P>
* Thread interruption is applied in this example. There are two ways to interrupt the thread:
* <Ul>
* <Li> use the interrupt () method </li>
* <Li> use an infinite loop in run (), and then use a Boolean mark to control the stop of the loop </li>
* </Ul>
* In addition, internal classes and anonymous internal classes are used separately.
