Thread state for a thread which has not yet started.
RUNNABLE

TERMINATED
public static final Thread.State TERMINATED
Thread state for a terminated thread. The thread has completed execution.
TIMED_WAITING
public static final Thread.State TIMED_WAITING
Thread state for a waiting thread with a specified waiting time. A thread is in the timed waiting state due to calling one of the following methods with a specified positive waiting time:
Thread.sleep
Object.wait
with timeoutThread.join
with timeoutLockSupport.parkNanos
LockSupport.parkUntil
WAITING
public static final Thread.State WAITING
Thread state for a waiting thread. A thread is in the waiting state due to calling one of the following methods:
Object.wait
with no timeoutThread.join
with no timeoutLockSupport.park
A thread in the waiting state is waiting for another thread to
perform a particular action.
For example, a thread that has called Object.wait()
on an object is waiting for another thread to call
Object.notify()
or Object.notifyAll()

is waiting for a specified thread to terminate.
