What is the difference between the sleep () method of a thread and the yield () method?

The 1.sleep () method gives other threads the opportunity to run without taking into account the priority of the thread, thus giving the low-priority thread a chance to run

The 2.yield () method only gives the same priority or higher priority thread the opportunity to run

3. The thread executes the sleep () method and then goes into a blocking (blocked) state, and the yield () method is transferred to the Ready state

The 4.sleep () method declaration throws interruptedexception, and the yield () method does not declare any exceptions

5.sleep () method has better portability than yield () method (related to OS CPU scheduling)
