"Mark the unused object for garbage collection and collect it."
As per the algorithum there will be two thread.
One will mark all the unreferenced object for garbage collection and the other will reclaim the marked object memory.

Mark and Sweep garbage collection is 2 phase algorithm.In the first phase, it finds and marks all accessible objects recursively and in second phase it scans through the heap and reclaims all the unmarked objects.

Mark and sweep algo won't reclaim unrefenced objects immediately . It starts reclaiming when available memory exhausting.
