1, static sleep () for the process to pause the specified time, the unit is milliseconds
2. A thread is marked as a daemon thread, and the JVM automatically terminates at the end of all non-daemon threads
3, the thread has the priority, the greater the number of priority higher. If the priority is the same, the flow execution

This week is rather busy. More experiments. Chapter 12 does not look very much, the concrete will fill in. Feel that the 13th chapter is relatively simple compared to before
