Thread Sleep wait Join

Current thread static method:

1.sleep: Blocks the current thread for a period of time, active behavior, does not allocate to CPU resources, and does not release locks.

2.yield: Blocks the current thread for a period of time, active behavior, does not allocate to CPU resources, and does not release locks. (different from sleep is to give up CPU resources, other high-priority or low-priority threads are executed)

Current thread instance method:

1.join: Block the calling thread and let the calling thread wait over there. The thread instance blocks the calling thread until the thread execution finishes.

2.wait: Blocks the current thread for a period of time, releases the lock resource, and waits for a signal notification. In. NET implements such as Lock () {monitor.wait ()}; Autoresetevent.waitone ())
