Or it does NOT use Heap "Data-Structure". The name given to the Memory for allocation(Pool of Memory) is just known as "Heap"?
If yes, then is that any relation between Heap Data-Structure and Heap as in Pool of Memory?

Heap space is used for the dynamic memory allocation of Java objects and JRE classes at runtime. New objects are always created in heap space, and the references to these objects are stored in stack memory. These objects have global access and we can access them from anywhere in the application.
The heap is a memory used by programming languages to store global variables. By default, all global variable are stored in heap memory space. It supports Dynamic memory allocation. The heap is not managed automatically for you and is not as tightly managed by the CPU.
The Heap Space contains all objects are created, but Stack contains any reference to those objects. Objects stored in the Heap can be accessed throughout the application. Primitive local variables are only accessed the Stack Memory blocks that contain their methods.
A heap is a special data structure in Java. A heap is a tree-based data structure and can be classified as a complete binary tree. All the nodes of the heap are arranged in a specific order.
There's no relation between heap memory and heap the data structure. They just happen to share the same name.
