Does variable = null set it for garbage collection

Question

Help me settle a dispute with a coworker: Does setting a variable or collection to null in Java aid in garbage collection and reducing memory usage? If I have a long running

Answer 1

It is a good to have. When you set objects to null, there is a possibility that the object can be garbage collected faster, in the immediate GC cycle. But there is no guaranteed mechanism to make an object garbage collected at a given time.
