Java and Heap ADT

Usually we say that when we create an object, it is actually created in <b>the</b> heap.

Now, I understand the standard Heap ADT but I am not sure about what the java heap is? Basically, I want to understand how is an object stored in "heap".

Any ideas?

The heap is just an area of memory in the computer's RAM. It doesn't have anything to do with "heap" as a data structure. If you look at the Wikipedia page for 'Heap' you'll see that it has two different meanings:
  • heap (data structure), a tree-like data structure
  • The heap (or free store) is the area of memory used for dynamic memory allocation
  • So, the same word, two different meanings.
