Which parts of memory are used for dynamic data allocation in the Heap?

In Java, dynamic memory allocation occurs in an area called the Heap. The Heap is divided into several parts used to manage the lifecycle of objects:

• Young Generation — where new objects are created. It is divided into:

  • Eden Space — the main area for new objects.
  • Survivor Spaces (S0 and S1) — objects that have survived garbage collection in Eden are moved here.

• Old Generation — objects that live longer are moved here after several garbage collection cycles in the Young Generation.

• Metaspace — an area for storing class metadata, not part of the Heap, but important for dynamic allocation.
