The Thread object

[ravinderSingh singh]

Hello,

Is a thread only represented by a single Thread object?

In other words, when you invoke the Thread.currentThread() method does this method return a reference to the same Thread object that was used to create the thread?

One more thing, is the Thread object representing a thread ever garbage collected if there are no references to the object?

Thanks

The answer to your first two questions are "yes". There is a single Thread object for each thread.

"Live" Thread objects always belong to a ThreadGroup, which keeps references to them. Therefore, a runnable Thread can never be garbage collected. They become eligible for collection after they are stopped.

gc will not collecte Thread if Thread is working. Even when there is no references to the Thread object.
