Java Garbage Collector for stack

Is garbage collector responsible for stack removal?

Does it also deallocate memory for static/constant variables?

example:

class A
{
   void fun(){
   int x = 100;
   static int y = 200;
   final int z = 300;
   }
}

Is all three variable's memory deallocated when function gets completed?

Static fields will not be eligible for garbage collection as long as the class they live in is loaded. And according to Oracle docs:

A class or interface may be unloaded if and only if its defining class loader may be reclaimed by the garbage collector.

Basically garbage collection deallocates memory for all objects that are no longer referenced by any other object in the JVM. So it doesn't matter if it is a static or instance field or a local variable.

The garbage collector is responsible for orphan objects on the heap.

Have a look at this Oracle tutorial Java Garbage Collection Basics. It explain the GC basics.
