Thread States

  • We can get the state of a thread by calling getState() method on them.

  • BLOCKED : A thread has suspended execution because it is waiting to acquire a lock.

  • NEW: A thread has not begun execution.

  • RUNNABLE: A thread that either is currently executing or will execute when it gains access to the CPU.

  • TERMINATED: A thread that has completed execution.

  • TIMED_WAITING: A thread that has suspended execution for a specified period of time, such as when it has called sleep(). This state is also entered when a timeout version of wait() or join() is called.

  • WAITING: A thread that has suspended execution because it is waiting for some action to occur. For example: it is waiting because of a call to a non-timeout version of wait() or join().
