Heap Memory :
Class instances and arrays are stored in heap memory. Heap memory is also called as shared memory.
As this is the place where multiple threads will share the same data.
Non-heap Memory :
It comprises of ‘Method Area’ and other memory required for internal processing. So here the major player is ‘Method Area’.
Stack Memory :
The two sections other from the code segment in the memory are used for data. The stack is the section of memory that is allocated for automatic variables within functions.
Data is stored in stack using the Last In First Out (LIFO) method. This means that storage in the memory is allocated and deallocated at only one end of the memory called the top of the stack. Stack is a section of memory and its associated registers that is used for temporary storage of information in which the most recently stored item is the first to be retrieved.
