What are the difference between heap and stack memory in java ?

Answer 1

The Stack is the part in memory where local variables and function calls space is allocated. Thats why if you create a recursive function without a base case you will get a StackOverFlowError in java as each call takes up more of the available space of the stack until it runs out

The Heap is where objects are stored.

Answer 2

Stack is a static memory, where heap is a dynamic memory
