![]() The heap may be of a fixed size or may be expanded as required by the computation and may be contracted if a larger heap becomes unnecessary. The Java Virtual Machine assumes no particular type of automatic storage management system, and the storage management technique may be chosen according to the implementor’s system requirements. Heap storage for objects is reclaimed by an automatic storage management system (known as a garbage collector) objects are never explicitly reallocated. The heap is created on a virtual machine start-up. The heap is the run-time data area from which memory for all class instances and arrays is allocated. The Java Virtual Machine has a heap that is shared among all Java Virtual Machine threads. So now coming onto heap memory, the heap is a location in memory used by the Java Virtual Machine (JVM). Task Engine runs on JVM (Java Virtual Machine). Whenever a java program is executed in the java virtual machine it uses the heap memory to manage the data. All the dynamic allocations go into heap memory and the rest of the static allocations and variables allocations go into stack memory. ![]() There are two types of memory stack memory and heap memory.
