To cut a long story short: you can't LABEL allocated memory on the heap. In stack you can. NAME vs ADDRESS.

S T A C K A L L O C A T I O N (NAME)

Int x = 4 -> you actually do:

1 Allocate memory on stack with size of int.

2 Give this memory location NAME 'x'.

3 Put value 4 in x.

H E A P A L L O C A T I O N (ADDRESS)

Student Student1 = new Student('Peter') -> you actually do:

1 Allocate memory on Heap with size of object Student.

(You can't assign a name to this location on the heap)

2 Copy the the object's location ADDRESS into reference Student1.

3 Put value 'Peter' in the objects field

So if you can't access a location by NAME you can do it by ADDRESS.

To cut a long story short: you can't LABEL allocated memory on the dynamic heap. In static stack you can. NAME vs ADDRESS.
