Hi abs,
The API states:
public static enum Thread.State
extends Enum<Thread.State>
A thread state. A thread can be in one of the following states:
NEW
A thread that has not yet started is in this state.
RUNNABLE
A thread executing in the
Java virtual machine is in this state.
BLOCKED
A thread that is blocked waiting for a monitor lock is in this state.
WAITING
A thread that is waiting indefinitely for another thread to perform a particular action is in this state.
TIMED_WAITING
A thread that is waiting for another thread to perform an action for up to a specified waiting time is in this state.
TERMINATED
A thread that has exited is in this state.
A thread can be in only one state at a given point in time. These states are virtual machine states which do not reflect any operating system thread states.
I think it is unable to determine whether it is RUNNABLE or RUNNING, because the context-switching is operating system dependent, therefore there is no such constant named RUNNING, which is why Thread.yield() method have not guaranteed behavior.
Hello Ranchers please confirm
Thank You
