My program spawns many threads. Each thread will allocate a byte array of size 100,000. Do I need to null the array within each worker thread as they are about to die ?

An object becomes eligible for garbage collection when there is no live thread that holds a reference to the object.

Setting variables to null in a thread that's going to stop immediately after that doesn't help anything for garbage collection.
