Stack-memory has minimum storage space in comparison to the Heap-memory.Memory allocation and de-allocation is faster in comparison to the Heap-memory allocation.Stack memory is considered safe in comparison to the heap memory allocation because the data stored is accessed by owner thread.The corresponding error is triggered by JVM, if the stack memory is completely filled.It simply allocates or de-allocates the memory by default as soon as the corresponding method finishes its execution.It’s a temporary memory allocation where the data members can be accessed only if the method( ) containing them is running.To further discuss the Java Heap Vs Stack it is important to understand some essential points for advanced application development. The size of the memory stack is less in comparison to the heap memory size. A stack is mentioned as static memory allocation. Stack memory works on the Last-In-First-Out (LIFO) approach. The local variables are stored and method invocations are available in the specific memory named Stack. It is usually located at the bottom of the address, while garbage is collected once the heap size becomes full. This memory is later used for creating objects as well as instances, and this memory is named Java heap. Java virtual machine (JVM) allocates some part of the memory from the operating system.
