java objects do not have same lifetime as primitives

Primitives are created directly on the stack and disappear when they go out of scope. There is no garbage collection of them.

my stupid asking that whether garbage collection wont be done on stack..??

The stack has its 'own management', the garbage collector acts on the heap.

Stack does not need garbage collection due to is structure. Nothing is randomly allocated, so nothing needs to be deallocated. Stack does not provide random access from any context, like heap. You create and remove stack frames in first-come-last-served order. You really need to learn how stack works, because understanding of it is very important everywhere in programming.

See for instance: "Stack and Heap memory in Java" at Stack Exchange[^].
