Heap

At the heart of the JVM lies the heap, a shared space among all JVM threads, and the dynamic runtime data area responsible for allocating memory to all class instances and arrays. As a foundational component created during virtual machine startup, the heap plays a pivotal role in executing Java applications.

An automatic storage management system, commonly known as a garbage collector, orchestrates memory management within the heap. Notably, objects in the heap are never explicitly deallocated, relying on the automatic system to reclaim storage. The JVM remains agnostic to a specific storage management technique, allowing flexibility in its implementation to cater to varied system requirements. The heap’s size can be fixed or dynamically adjusted based on computational needs, expanding or contracting as necessary. This adaptability, combined with non-contiguous memory allocation, ensures efficient utilization.
