2, Ready State (Runnable): Executable state, after the thread object is created, the other thread invokes the object's start () method, and the thread is started. Is in a ready state and can be executed at any time by CPU scheduling.

3, running State (Running): The thread gets to the CPU being executed. A thread can only move from a ready state to a running state, not from another state.

4, blocking State (Blocked): The blocking state is that the thread has abandoned the use of the CPU for some reason and temporarily stopped running. Blocking is divided into three situations:

(b) Synchronous blocking: threads are getting
