Where does the JVM store objects during program execution?

In JVM, objects during program execution are stored in the heap — a memory area allocated for dynamic object allocation.

The heap is divided into several parts, for example:

• Young Generation — for newly created objects.
• Old Generation — for objects that live longer.

Besides the heap, JVM has other memory areas, such as the stack for method calls and local variables, but objects are specifically placed in the heap.
