What happens to objects in dynamic memory allocation, and which of them end up in the heap?

In Android, objects created dynamically (for example, using new) are placed in a memory area called the heap. The heap is a region of memory for dynamic allocation, where objects with an indefinite lifespan are stored.

What happens to such objects:

• When an object is created, it is allocated in the heap.
• A reference to the object is stored in the stack or in other objects.
• When there are no more references to the object, the garbage collector frees the memory occupied by that object.

Thus, all objects created dynamically (for example, class instances) go into the heap. Local primitive variables and references are stored in the stack.

Example:

public void example() {
    String s = new String("Hello"); // String object is created in the heap
    int x = 5; // primitive is stored in the stack
}

The Android garbage collector manages heap memory by freeing objects that are no longer used.
