3. Heap:A general memory pool (also located inRamArea), usedStore all Java objectsStack has the following advantages:The compiler does not need to know how many storage areas are allocated from the heap, nor how long all the data stored in the heap will survive in the heap.. Therefore, it is flexible to allocate storage in the heap. But when you need
Example of using the Data Object Persistence storage module pickle in Python, pythonpickle
