Diffience between Stack and Heap Memery in java ?

reference

Sr. No.	Key	Stack	Heap Memory
1	Basic	Stack memory is used to store items which have a very short life like local variables, a reference variable of objects	Heap memory is allocated to store objects and JRE classes.
2	Ordering	The stack is always reserved in a LIFO (last in first out) order	Heap memory is dynamic allocation there is no fixed pattern for allocating and deallocating blocks in memory
3	Size	We can increase stack memory size by using JVM parameter -XSS	We can increase or decrease heap memory size by using JVM option -Xms and -Xmx
4	Visibility	Variables are visible to only to owner thread	It is visible to all threads
5	Exception	JVM will throw java.lang.StackOverFlowError	JVM will throw java.lang.OutOfMemoryError
