When it comes to memory management in Java, two fundamental concepts that every developer should understand are Heap Memory and Stack Memory. Grasping the difference between these two is crucial for writing efficient code and avoiding issues like memory leaks or overflow.

💡 Stack Memory
Stack Memory is used to store local variables and method calls. Each time a method is invoked, a new "stack frame" is created to store the method's variables and the return address. Once the method completes, the frame is removed, instantly freeing up the memory. The Stack is highly efficient but limited in size.

📂 Heap Memory
Heap Memory, on the other hand, is where objects in Java are stored. Unlike the Stack, the Heap has a larger size and allows for dynamic memory allocation. Objects allocated on the Heap remain there until there are no more references to them, at which point the Garbage Collector kicks in to free up that memory. The Heap is more flexible, but accessing it is slightly slower compared to the Stack.

⚖️ Why Does It Matter?
Understanding how Stack and Heap memory work can help you optimize resource usage and avoid issues like StackOverflowError (when the Stack is full) or OutOfMemoryError (when the Heap can't allocate more objects). Knowing when and where to allocate memory is essential for creating robust and efficient Java applications.
