How are thread identified in threadpool

[Abrahim Daver]

Hi All,

I would like to know, if I set same name for each thread created in thread pool using Thread.currentThread().setName(). Will it cause any problem?
How are threads recognized in threadpool ? by Name OR id OR ???

Thanking you in advance.

Try it and find out.

(Hint: you need to set the name in the constructor.)

I am not sure what do you intend by saying "recognized".
I assume you are talking about the ThreadPool Implementation in the jdk, so, I would answer in terms of ThreadPoolExecutor.
It maintains a HashSet of workers(A runnable implementation) and there is no reference to the Thread created. Workers pull tasks from the work queue and execute them.
There is no managing entity that picks up a thread and instructs to execute a task. So, I dont think anybody needs to recognize any thread as such.

Every thread in the JVM is assigned a unique identifier, so, assigning same name does no harm to the thread execution/management but it will create problems for people debugging the thread dumps.
