In Java, how do you determine if a thread is running?

Question

How do you determine if a thread is running?

Answer 1

Check the thread status by calling Thread.isAlive.

Answer 2

Thread.isAlive()

Answer 3

You can use: Thread.currentThread().isAlive();. Returns true if this thread is alive; false otherwise.

Answer 4

I think you can use GetState(); It can return the exact state of a thread.

Answer 5

To be precise,

Thread.isAlive() returns true if the thread has been started (may not yet be running) but has not yet completed its run method.

Thread.getState() returns the exact state of the thread.

Answer 6

Have your thread notify some other thread when it’s finished. This way you’ll always know exactly what’s going on.
