8. *sleep () is a static method that belongs to a class that is used to block the current thread
10. *join () is a thread that synchronizes threads, such as calling T.join () in a thread to indicate that the T thread executes and then executes the current thread
12. *interrupt () sets a flag to a thread indicating that the thread has been interrupted, but this flag will be cleaned up when the exception is captured
14. * So in the catch clause, the flag is false
