Thread for "7.14" threads

1): The difference between the Ready (Runnable) and blocking (Blocked) of the process

When the processor is idle, the thread in the ready state gets the processor resources and goes into operation, and when the yield () is called, the running thread is in the ready state.

When a thread is blocked, even if the processor is idle, the process will not be allocated CPU resources until the relevant action is completed (sleep time, I/O input completed, synchronization lock received, notification

, resume ()), sleep (), Waiting for I/O input, waiting for a sync lock, waiting for notification, suspend (), and so on, causes the process to go into a blocking state.
