- Enclosing class:
public static enum Thread.State extends Enum<Thread.State>
A thread that has not yet started is in this state.
A thread executing in the Java virtual machine is in this state.
A thread that is blocked waiting for a monitor lock is in this state.
A thread that is waiting indefinitely for another thread to perform a particular action is in this state.
A thread that is waiting for another thread to perform an action for up to a specified waiting time is in this state.
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.

Enum Constant Details
NEWpublic static final Thread.State NEWThread state for a thread which has not yet started.
RUNNABLEpublic static final Thread.State RUNNABLEThread state for a runnable thread. A thread in the runnable state is executing in the Java virtual machine but it may be waiting for other resources from the operating system such as processor.
BLOCKEDpublic static final Thread.State BLOCKEDThread state for a thread blocked waiting for a monitor lock. A thread in the blocked state is waiting for a monitor lock to enter a synchronized block/method or reenter a synchronized block/method after calling
WAITINGpublic static final Thread.State WAITINGThread state for a waiting thread. A thread is in the waiting state due to calling one of the following methods:
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.notifyAll()on that object. A thread that has called
Thread.join()is waiting for a specified thread to terminate.
TIMED_WAITINGpublic static final Thread.State TIMED_WAITING
TERMINATEDpublic static final Thread.State TERMINATEDThread state for a terminated thread. The thread has completed execution.
valuespublic static Thread.State values()Returns an array containing the constants of this enum type, in the order they are declared.
