Do you mean that when the current thread leaves a synchronized block, it
will release the lock and then other threads will have chances to obtain
the lock?

Do you mean using yield method will idle the CPU? If it is true, do you
know how to write a simple program to test that sleep method will not idle
CPU, and at the same time yield method will idle CPU?


Have a nice weekend,
