In Java, understanding Heap Memory and Stack Memory is essential for writing efficient code. These are the two main areas where memory is managed, and knowing how they work can prevent issues like memory leaks or crashes.

Stack Memory stores local variables and tracks method calls. When a method is called, a "stack frame" is created to hold its variables and return address. Once the method finishes, this frame is removed, instantly freeing up the memory. The Stack is fast but has limited space.

Heap Memory is where Java objects live. It’s larger than the Stack and supports dynamic memory allocation. Objects stay in the Heap until they are no longer needed, at which point the Garbage Collector removes them to free up space. The Heap is flexible, but accessing it is a bit slower compared to the Stack.

Understanding Stack and Heap memory helps you optimize resource usage. It can prevent errors like StackOverflowError (when the Stack is full) or OutOfMemoryError (when the Heap runs out of space). Knowing where to allocate memory is key to building efficient and stable Java applications.
