Does thread.yield() lose the lock on object if called inside a synchronized method?

Question

I understand that Thread.currentThread().yield() is a notification to thread scheduler that it may assign cpu cycle to some other thread of same priority if any

Answer 1

No. Thread.yield() is not like Object.wait(). It just gives up control to allow a thread switch. It will have no effect on the concurrency of your program.

There is no guarantee which thread the scheduler will run after a yield.
