reference vs pointers

  Asked By: Daryl    Date: Oct 22    Category: Java    Views: 758
  

i read in one of the books that java does not
implement pointers . i.e i would not be able to access
physical memory address.

But i read that java has an alternative called the
reference to access objects and variables.

what is the essential difference between a pointer
and a reference .

A pointer is a memory  location that contains a reference  to a
variable. That's about it.

Java does not have pointers in the sense that you cannot declare them.
In another sense, every object in Java is a pointer and Java just lets
you treat it as if it were the actual object. You don't have to worry
about deleting the objects  due to garbage collection.
