Purpose of garbage collection
The garbage collection process is to identify the objects which are no longer referenced or needed by a program so that their resources can be reclaimed and reused. These identified objects will be discarded.
Famous Quotations
Never argue with a fool, onlookers may not be able to tell the difference.
