![]() As a result, the heap segment can be requested and released whenever the program needs it. What are the differences between Stack and Heap, A stack is an abstract data structure that is used for memory allocation. Difference between Java Heap Space and Stack Memory. ![]() The stack is a specific part of a computer's memory that is used to store information about local variables and function calls. Memory allocated to heaps can be dynamically allocated, unlike memory allocated to stacks. Author Name: Elliot Brenya Sarfo (Me) The Java stack and heap both are used to store information but each have a different uses. Compared to heap, stack is only used for the execution of a single thread versus being globally accessible and shared with all threads. The Heap & the Stack In Java, local variables are always allocated from the stack, while arrays and objects are always allocated from the heap. During the execution of a program, data and instructions are retrieved from memory using these addresses. ![]() ![]() It consists of several cells, each of which has a specific address indicating its location. Forgive me for adding an answer to such an old question - The current answer is great, but misses a couple of edge cases because of static code and Java 8 updates.
