Class Overview

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.
