Does a garbage collector collect stack memory, heap memory, or both?

Question

I read lot of articles about garbage collection and almost all article tells about heap memory. so my question is \"garbage collection collects stack memory or heap memory or bo

Answer 1

The stack is called a "stack" precisely because it is a zone of memory which is managed with a "stack policy", aka LIFO (as Last In, First Out). If allocation on the stack was not done in "the stack way" it would not be called a stack but heap.

Garbage Collection was invented in order to cope with the problem of allocating things on a heap, i.e. such that you cannot predict which parts will be released first. GC is meant for memory allocation problems where stack management is not sufficient.
