Can you explain the differences between heap memory and stack memory when working with programs?

The stack and heap memory differ in the way they are allocated and managed:

• Stack is a memory area where local variables and function parameters are stored. Allocation and deallocation of memory happen automatically when entering and exiting functions (LIFO — last in, first out). The stack is limited in size and very fast.

• Heap is a memory area for dynamic allocation, where objects are created and destroyed manually or with the help of a garbage collector. Memory in the heap can be of arbitrary size and lives longer than the stack, as long as there are references to it.

Example: in Android, when working with Java, objects are created in the heap, while local variables of methods are stored on the stack.
