Question

java线程执行yield（）后就会让出cpu
那之后如何恢复啊？

Answer 1

Yield is not sure to give up the CPU, and does not need to be restored, just wait for scheduling. This method is generally rarely used.

Answer 2

Thanks for correcting me
I misremembered

Answer 3

Wait for the thread scheduler to allocate CPU time slices to you later. But calling the yield method is just a suggestion, telling the thread scheduler that my work is almost done and that other threads of the same priority can use the CPU. There is no mechanism to guarantee adoption.
