Java: do I need to protect the Thread object from the garbage collector?

After

{
Thread t = new Thread();
t.start();
}

Is the Thread object a candidate for the GC?

If it is running, it is not suitable for the GC - code that works may request Thread.currentThread(), in the end.

If you just created it but did not start it, follow these steps:

{
    Thread pointless = new Thread();
}

then I suspect that he will be entitled to the GC - but it’s rather unusual to create a thread without starting it. (I assume that the exception could be thrown before you got it to start it ...)

You only need to protect Thread if you want to save it after its completion. It cannot be GC'ed during its operation (or anything that uses Thread)
