The garbage collector uses this algorithm to free memory when an object is unreachable, rather than a zero referencing object. The garbage collector will first find all the global objects or root objects and will find all the references to these global objects and references to the reference object, and so on.
How does developer informs the garbage collector that his object is no longer required?
Garbage collector reclaims objects that are no longer being used, clears their memory, and keeps the memory available for future allocations. This is done via bookkeeping the references to the objects.
